Contributions to the theory and practice of cold rolling

The development of a comprehensive computerized model for cold rolling is described. Rolling forces, torques, forward slip, temperatures of rolls and strip, thermal cambers of rolls, as well as strip thickness profile and flatness, are predicted. The model is applicable to both basic and applied studies of the rolling process. Its primary purposes are to aid in optimizing performance of existing mills, in the design of new cold mills, and in devising open-loop and closed-loop automatic flatness-control systems.

Process R & D—the noranda process

The development of the Noranda Process, which culminated in the world's first continuous copper smelter, began twenty years ago, in 1964. The metallurgical development of the process is traced from the vantage point of the researcher. Transport phenomena and physical chemistry aspects are discussed, with reference to the state of knowledge, then and now. Some of the pitfalls encountered in developing the process from the conceptual through the laboratory and pilot plant stages are illustrated. Finally, the process is examined as a case history of successful innovation. The Extractive Metallurgy Lecture was authorized in 1959 to provide an outstanding man in the field of nonferrous metallurgy as a lecturer at the annual AIME meeting. Dr. PETER TARASSOFF received his B. Eng. in Metallurgical Engineering from McGill University in 1956 and his Sc.D. in Chemical Metallurgy from Massachusetts Institute of Technology in 1962. He has also participated in the Management Development Program, 1980, at Northeastern University. He has been with the Noranda Research Centre, Quebec, since 1964, and currently holds the title of Director of Research and Development at Noranda.

Aspects of progress in the science of pyrometallurgy

The Symposium of the Faraday Society in 1948 entitled “Physical Chemistry of Process Metallurgy” occurred at a time when the science of pyrometallurgy was just beginning an era of rapid development. This lecture discusses the growth of the subject in the ensuing 25 years showing that a profound increase in our range of understanding and of factual information has taken place. The knowledge which has been gained now provides a good general framework for the industrial application of principles and for teaching at the University level. The social and intellectual climate of the times, however, appears to be leading to a slow-down in the pursuit of fundamental knowledge, in this as in many other applied scientific fields, and the case is argued for a renewal of effort. The Extractive Metallurgy Lecture was authorized in 1959 to provide an outstanding man in the field of nonferrous metallurgy as a lecturer at the annual AIME meeting. C. B. ALCOCK is Chairman of the Department of Metallurgy and Materials Science at the University of Toronto. He is a 1944 graduate of the Chemistry Department of London's Imperial College. He received his doctorate in chemical metallurgy from London University in 1955. After a short spell with the British Iron and Steel Research Association he was appointed Investigator in the Nuffield Research Group of the Royal School of Mines in 1950. Joining the academic staff of the Metallurgy Department in 1953 as a Lecturer, Dr. Alcock was a Reader in 1961 and a Professor of Metallurgical Chemistry in 1965. Dr. Alcock is a former Science Research Foundation Professor of the Carnegie Institute of Technology and of North Carolina State University. He was a Ford Visiting Professor at the University of Pennsylvania in 1965. Dr. Alcock's research interests are in high temperature chemistry of metal and ceramic systems. He is a Fellow of the Institution of Mining and Metallurgy (London).     

Grain boundary cracking

A chronological summary is given of the various types of grain boundary fracture found in metals. In each case, there is an impurity that adsorbs at the new (fracture) surface being formed. For the case of Fe-P alloys, a quantitative argument can show that adsorption of phosphorous on the free surface greatly reduces the barrier to void nucleation compared to that in the absence of phosphorous. The same or larger reduction would appear for any other element, which adsorbs more strongly than phosphorous and displaces it at the surface. Such an argument is shown to explain a great many cases of dimpled grain boundary fracture in strong alloys undergoing creep or hydrogen attack. The reduction in surface energy can also lead to a smooth grain boundary fracture (no void nucleation), in which diffusion of solute to the new surface limits crack growth. Numerous examples of this are also discussed. Dr. Shewmon studied metallurgical engineering at the University of Illinois (B.S. 1952) and Carnegie Institute of Technology (Ph.D. 1955). His first job was at the Westinghouse Research Laboratory, where he studied thermal diffusion in alloys and surface diffusion. In 1958, he moved to the Carnegie Institute of Technology, where he served as a professor until 1967. The text “Diffusion in Solids” was published in 1963. An NSF Fellowship was used to study at Professor C. Wagner’s Max Planck Institute (Goettingen, Germany) in 1963. From 1968 to 1973, he was at Argonne National Laboratory, serving successively as Associate Director of the Metallurgy Division, Associate Director of the EBR-2 Project, and Director of the Materials Science Division. The text “Transformations in Metals” was published in 1969. Materials behavior in fast breeder reactors was the main theme of his work during this period. He was the director of the Division of Materials Research at the National Science Foundation from 1973 to 1975. From 1975 to 1993, he was Professor at Ohio State University in the Department of Metallurgical Engineering (later Materials Science and Engineering), serving as Chairman from 1975 to 1983. Research interests during this period were hard particle erosion and hydrogen-induced cracking of steel (“hydrogen attack”). From 1977 to 1993 he served on the Advisory Committee on Reactor Safety for the United States Nuclear Regulations Committee, serving as Chair for three of those years. Dr. Shewmon was elected to the National Academy of Engineering in 1979 and has been awarded the standing of Fellow in TMS, ASM, ANS, and AAAS.

He received the Distinguished Alumnus Award of the University of Illinois in 1981 and a Humboldt Foundation Senior Scientist Prize in 1984. The Edward DeMille Campbell Memorial Lecture was established in 1926 as an annual lecture in memory of and in recognition of the outstanding scientific contributions to the metallurgical profession by a distinguished educator who was blind for all but two years of his professional life. It recognizes demonstrated ability in metallurgical science and engineering. The Institute of Metals Lecture was established in 1921, at which time the Institute of Metals Division was the only professional division within the American Institute of Mining and Metallurgical Engineers. It has been given annually since 1922 by distinguished people from this country and abroad. Beginning in 1973 and thereafter, the person selected to deliver the lecture will be known as the “Institute of Metals Division Lecturer and R.F. Mehl Medalist” for that year.     

Of Perspectives,Issues, and Politics in Materials Technology

Recognizing the pervasive importance of materials science and engineering (MSE) to practically every facet of man’s life, this lecture takes a broad view of the origin and technical trends and achievements in MSE, briefly reviewing its history and relationship to society over many millennia, to the present day, with specific examples. Major emphasis, however, is placed on modern MSE as related to current national issues, using as illustrations of the latter natural resources, industry and the economy, research and development, education, and technology transfer. The discussion of these areas leads to consideration of the role of the Federal Government and the importance of and need for a coherent national policy to deal with critical issues, many of which are listed herein. Some important steps by the Government fostering high level coordination as well as cooperation among government, industry, and academe are cited. Having thus illustrated the pervasive and vital impact of MSE on society, and its current esteemed recognition and position of influence, the lecture concludes that in this period of global change — social, economic, and technological — there is a challenge to MSE to respond beneficially to societal needs more than ever before. The opportunity and mechanisms now exist. Greater participation in the public and political arenas, with mutual education, is indicated. NATHAN E. PROMISEL received his Bachelor of Science and Master of Science Degree at the Massachusetts Institute of Technology, did his doctorate work at Yale University, and received an Honorary Doctor of Engineering Degree at Michigan Technological University.

The science and technology of steelmaking—Measurements, models, and manufacturing

In our efforts to characterize and improve the performance of an existing steelmaking process or in our quest to generate useful knowledge as a basis for the development of new manufacturing routes, measurements and models should be considered as two interdependent requirements. Without measurements, our models are incomplete and unsatisfactory. Without models, we fail to realize, or perhaps even comprehend, the potential significance of our measurements. Sometimes in our enthusiasm, we construct sophisticated elegant models and forget the reality of the actual manufacturing process. In this computer age, we need to remember again the importance of observations and accurate measurements. In addition, as engineers and applied scientists, we have an obligation and a responsibility to facilitate the transfer of new knowledge into the realm of operating practice. During this process of generation, evaluation, and communication of new knowledge, the knowledge exchange step is perhaps the most difficult. In this context, the preeminent aim of collaborative activities between our educational institutions, industrial organizations, government funding agencies, and professional societies is to ensure the availability of high-quality people who not only understand the fundamental aspects and practical implications of their discipline, but also are fully equipped with the essential skills of communication that will enable them to participate throughout their career in this most challenging and satisfying activity, the science and technology of steelmaking. The Brimacombe Memorial Lectureship was established in 1999 by the Process Technology Division of the Iron & Steel Society to honor Dr. J. Keith Brimacombe’s outstanding accomplishments in the area of process metallurgy, his dedication to the steel industry, and his profound effect on people in the industry; and also to acquaint members, students, and engineers with the many exciting opportunities that exist in the area of process metallurgy and to inspire them to pursue careers in this field. Professor McLean obtained his degrees in Applied Chemistry and Metallurgy from the University of Glasgow and the Royal College of Science and Technology, now the University of Strathcylde.

He was appointed Professor Emeritus at the University of Toronto in 2002.     

The greening of materials science and engineering

The field of materials science and engineering is advancing at a revolutionary pace. It is now generally recognized as being among the key emerging technological fields propelling our world societies into the twenty-first century. The driving forces for this revolutionary pace are at once social, economic, political, and technological. For example, relatively recent changes in United States federal policies in environmental control, hazardous waste management, and energy conservation along with heightened international trade competition have resulted in major changes in material processing and use patterns. These changing patterns are creating new requirements for material developments, substitutions, and associated processes. This paper traces the emergence of materials policy and technological developments through four sub-periods of history: the birth and development of engineering in the United States (1825–1900), the evolution of a national research infrastructure (1900–1945), the evolution of a national science policy (1945–1973), and the intensification of global interdependency (1973-present). Future trends in materials developments and future policy requirements are outlined. Technical Resources, of TRW, Inc., began his professional career in 1954 as a research metallurgist and reactor project engineer with General Electric Co. at the Hanford Atomic Products Operation in Richland, WA. In 1965 he joined Battelle Memorial Institute as a manager of the metallurgy research department and three years later became manager of the fuels and materials department. In 1970 Dr. Bement joined the faculty of Massachusetts Institute of Technology as professor of nuclear materials. From 1974 to 1976 he served as a member of the U.S.-U.S.S.R. Bilateral Exchange Program in Magnetohydrodynamics and was the organizer and principal investigator of the M.I.T. Fusion Technology Program. In 1976 Dr. Bement became Director of the Materials Sciences Office of the Defense Advanced Research Projects Agency and in 1979 was appointed Deputy Under-Secretary of Defense for Research and Engineering.

Computer simulation of solidification processes—The evolution of a technology

The historical development of solidification modeling is traced, as applied to solidification processing. Clearly, the growth of this technology followed the computer explosion, particularly with regard to hardware. However, universities and government laboratories made substantial contributions in the software area, particularly in removing roadblocks to the further development of the technology and by creative examples. The commercial software houses have utilized these leading-edge developments, a practice continued and expanding today. Heat-transfer analyses by computer were initiated by utilizing the analog computer, which appeared to be a competing technology, but by the early 1960s, the digital computer had become the winner in larger-scale computation. A number of benchmark achievements followed over the next several decades. The evolution of this technology is documented, including predictions of solidification microstructure and resulting material properties. Future developments are projected. This lecture was presented to honor Edward DeMille Campbell (University of Michigan, Class of 1886), born in 1863, who was appointed Assistant Professor of Metallurgy in 1890. Dr. Campbell brought a strong interest in the study of the constitution of metals and alloys to the University of Michigan. In 1892, during a study of the composition of steel, he lost his eyesight in a laboratory explosion. Within five days, he returned to the University, and resumed his teaching and research. Over the next 30 years, he published 72 research papers, and developed a laboratory course in metallography. In 1924, working under the direction of Professor Campbell, William Fink discovered a new, tetragonal form of iron (martensite) in the first significant application of a new tool, X-ray diffraction, to physical metallurgy. It was these experiments that established the beginning of a strong tradition in physical metallurgy at the University of Michigan. In 1898, Campbell led the effort to establish Chemical Engineering at Michigan, becoming Professor of Chemical Engineering and Analytical Chemistry in 1902. In 1914, Campbell was appointed Director of the University’s Chemical Laboratory and Professor of Chemistry. Following his death in 1925, the American Society for Metals established this annual award in his name. The Edward DeMille Campbell Memorial Lecture was established in 1926 as an annual lecture in memory of and in recognition of the outstanding scientific contributions to the metallurgical profession by a distinguished educator who was blind for all but two years of his professional life.

Fluid flows in metallurgy—Friend or foe?

Fluid flows are an integral part of many metallurgical processing operations. They affect the viability, effectiveness, and efficiency of many reactors, be they physical or chemical, in nature. The performance characteristics of blast furnaces, steelmaking vessels, ladles, tundishes, and the molds of continuous casting machines are all strongly influenced by such flows of fluids. Similarly, the question of liquid metal quality, and cast microstructures, is bound up with the way fluids have flowed and interacted. In all these aspects, the evolution in our techniques and abilities to model single- and multiphase flows and their attendant heat- and mass-transfer processes has contributed significantly to our understanding, and ability, to control these processes, to design improvements, and to develop new processes. To be ignorant of such matters can doom a processing operation to the scrap heap of metallurgical failures. This article reviews some of the more important aspects of flows in metallurgical reactor systems associated with steel and aluminum processing, by way of a series of typical examples. Roderick I.L. Guthrie is the Director of the McGill Metals Processing Centre (MMPC) and the Macdonald Professor of Metallurgy in the Department of Mining and Metallurgical Engineering, McGill University (Montreal). Leaving Durham Cathedral School, as Head Chorister, in 1953, he later graduated from Nottingham High School in 1960, took an honors degree in metallurgy at the Royal School of Mines, Imperial College, in 1963, and went on to obtain a doctorate in process metallurgy in 1967, under the guidance of Professors Richardson and Bradshaw of the Nuffield and John Percy Research Groups. Since then, Dr. Guthrie has carried out pioneering research in process engineering metallurgy, on a multitude of topics related to the processing of iron and steel, and of light metals. As well as some 350 papers written in collaboration with his many graduate students, he also wrote the textbooks “Engineering in Process Metallurgy” and “The Properties of Liquid Metals” published by Oxford University Press, in 1990. Something of an inventor, Guthrie presently holds some 150 patents on a variety of inventions, one of which is in use, worldwide, for the detection of inclusions in liquid aluminum (LiMCA). Most recently, an in-situ sensor for the three-dimensional scanning of inclusions in liquid steel has been successfully accomplished, also based on the electric sensing zone technique, again in close collaboration with industrial colleagues. Dr. Guthrie’s most recent research interests are concerned with the high-speed, near-net-shape casting of sheet materials via twin-roll, and single belt, casting machines, and the possibility of bulk amorphous sheet materials. His career of 30 years at McGill University has been interspersed with 20 summers as a full-time research consultant to the steel and aluminum industries, plus a number of Visiting Professorships at the Universities of Tohoku, NTH, KTH, Carnegie Mellon, Greenwich, and Guildford. Dr. Guthrie is a Fellow of the Canadian Institute of Mining, a Fellow of the Royal Society of Canada, a Fellow of the Canadian Academy of Engineering, and a Distinguished Member of the Iron and Steel Society. He has been the recipient of numerous Best Paper Awards, including two Henry Marion Howe Medals of the ASM, two John Chipman Awards of the ISS, two Extractive Metallurgy Awards of the TMS, and three Light Metal Awards of TMS and CIM. He has served on the Board of Directors of the Metallurgical Society of Canadian Institute of Mining, Metals and Petroleum Engineers, being its President in 1992.     

Mechanical properties of thin films

The mechanical properties of thin films on substrates are described and studied. It is shown that very large stresses may be present in the thin films that comprise integrated circuits and magnetic disks and that these stresses can cause deformation and fracture to occur. It is argued that the approaches that have proven useful in the study of bulk structural materials can be used to understand the mechanical behavior of thin film materials. Understanding the mechanical properties of thin films on substrates requires an understanding of the stresses in thin film structures as well as a knowledge of the mechanisms by which thin films deform. The fundamentals of these processes are reviewed. For a crystalline film on a nondeformable substrate, a key problem involves the movement of dislocations in the film. An analysis of this problem provides insight into both the formation of misfit dislocations in epitaxial thin films and the high strengths of thin metal films on substrates. It is demonstrated that the kinetics of dislocation motion at high temperatures are expecially important to the understanding of the formation of misfit dislocations in heteroepitaxial structures. The experimental study of mechanical properties of thin films requires the development and use of nontraditional mechanical testing techniques. Some of the techniques that have been developed recently are described. The measurement of substrate curvature by laser scanning is shown to be an effective way of measuring the biaxial stresses in thin films and studying the biaxial deformation properties at elevated temperatures. Submicron indentation testing techniques, which make use of the Nanoindenter, are also reviewed. The mechanical properties that can be studied using this instrument are described, including hardness, elastic modulus, and time-dependent deformation properties. Finally, a new testing technique involving the deflection of microbeam samples of thin film materials made by integrated circuit manufacturing methods is described. It is shown that both elastic and plastic properties of thin film materials can be measured using this technique. The Institute of Metals Lecture was established in 1921, at which time the Institute of Metals Division was the only professional division within the American Institute of Mining and Metallurgical Engineers Society. It has been given annually since 1922 by distinguished men from this country and abroad. Beginning in 1973 and thereafter, the person selected to deliver the lecture will be known as the “Institute of Metals Division Lecturer and R.F. Mehl Medalist” for that year. WILLIAM D. NIX, Professor, obtained his B.S. degree in Metallurgical Engineering from San Jose State University, San Jose, CA, and his M.S. and Ph.D. degrees in Metallurgical Engineering and Materials Science, respectively, from Stanford University, Stanford, CA. He joined the faculty at Stanford in 1963 and was appointed Professor in 1972. In 1964, Professor Nix received the Western Electric Fund Award for Excellence in Engineering Instruction and, in 1970, the Bradley Stoughton Teaching Award of ASM. He received the 1979 Champion Herbert Mathewson Award and, in 1988, was the Institute of Metals Lecturer and recipient of the Robert Franklin Mehl Award of TMS-AIME. He was elected Fellow of the American Society for Metals in 1978 and elected Fellow of TMS-AIME in 1988. He also received a Distinguished Alumnus Award from San Jose State University in 1980, and he served as Chairman of the 1985 Gordon Conference on Physical Metallurgy. In 1987, he was elected to the National Academy of Engineering. In 1966, he participated in the Ford Foundation's “Residence in Engineering Practice” program as Assistant to the Director of Technology at the Stellite Division of Union Carbide Corporation. From 1968 to 1970, Professor Nix was Director of Stanford's Center for Materials Research. Professor Nix is engaged in research on the mechanical properties of solids. He is principally concerned with the relation between structure and mechanical properties of materials in both thin film and bulk form. He is coauthor of about 190 publications in these and related fields. Professor Nix teaches courses on dislocation theory and mechanical properties of materials. He is coauthor of “The Principles of Engineering Materials,” published in 1973 by Prentice-Hall, Incorporated, Englewood Cliffs, NJ.     

Drops and bubbles in extractive metallurgy

Drops and bubbles are of great importance to the extractive metallurgist in his attempts to speed up processes by the use of sprays, foams, and jets. In this lecture the ways in which bubbles bring about mass transfer in liquid metals and in slag metal reactions are described. The role of interfacial turbulence is considered together with the effects of bubble size and frequency and the properties of the slag and metal phases. Reactions between drops of metal and flowing gases are analyzed in terms of mass transfer in the reacting phases and of chemical steps at the interface. Recent results obtained on reactions involving metal drops falling through liquids are considered in relation to mass transfer models in which internal circulation plays an important part. The work described reports only one facet of the rapidly developing subject of Process Engineering which ought now to feature prominently in metalurgical education. Dr. F. DENYS RICHARDSON. Professor of Extraction Metallurgy. Department of Metallurgy, Royal School of Mines. Imperial College of Science and Technology, London, England, graduated in chemistry at University College, London, in 1933, and obtained a Ph.D. in physical chemistry in 1936. From 1937 to 1939 he was Commonwealth Fund Fellow at the University of Princeton. From 1946 to 1950 he worked as superintendent chemist at BISRA, building up the work of the chemistry department. He went to Imperial College in 1950 to found the Nuffield Research Group in Extraction Metallurgy and advance the study of chemical metallurgy at high temperatures. He received awards in recognition of his work on the thermodynamic properties of high-temperature systems with special reference to iron- and steelmaking and for his work on high-temperature chemical metallurgy. He was appointed Professor of Extraction Metallurgy at Imperial College in 1957, his objectives there being to establish the department as a research center for chemical and process engineering metallurgy, and to develop a metallurgy course in which these subjects receive as much attention as physical metallurgy. In 1963 he was elected a Fellow of the Metallurgical Society of the AIME, and in 1964 he gave the AIME Howe Memorial Lecture. Professor Richardson delivered the Hatfield Memorial Lecture in 1964, the May Lecture of the Institute of Metals in 1965, and the Wernher Memorial Lecture of The Institution of Mining and Metallurgy in 1967. He was elected a Member of Council of the Iron and Steel Institute in 1967, having been an Honorary Member since 1962. In 1968 he became a Vice-President of the Institution of Mining and Metallurgy. In that year he was also elected a Fellow of the Royal Society and awarded the Bessemer Gold Medal of the Iron and Steel Institute, both honors for his contribution to the understanding of the thermodynamics and kinetics of metallurgical processes. In 1970 the honorary degree of Doktor-Ingenieur was conferred on him by the Technische Hochschale, Aachen. The 1971 Extractive Metallurgy Division Lecture, “Drops and Bubbles in Extractive Metallurgy.” was delivered on Wedresday, March 3, 1971.     

Historical account of the contributions of E. C. Bain

This paper attempts to summarize some of Edgar Bain’s inspired contributions to metallurgy during a period of about a decade—surely one of the most intensely creative eras in the history of the profession. It is necessarily subjective and to some extent incomplete, but it hopefully provides a documentation of clear thinking about important practical and theoretical problems and of incisive experimentation to confirm critical hypotheses.

Nanotechnology: Scientific challenges and societal benefits and risks

The field of nanotechnology is developing rapidly, as are its practical application in society. In this article, we give examples that demonstrate the enormous potential that exists for this new class of materials, and for devices with critical dimensions of less than 100 nm. We also identify some of the challenges that need to be faced in order to fully realize the practical benefits of nanotechnology, and discuss possible risks that may come with this new technology. In all cases, the unique advantage of nanotechnology can be traced back to nanoscale physical and chemical properties that are quite different from those encountered in more traditional microscopic (micro) or macroscopic (macro) materials and devices. Unique nanoscale properties and behaviors are already being used to increase energy efficiency, improve healthcare, and strengthen national security. However, while progress is rapid, many challenges remain. These include manufacturing at the nanoscale, integration of nanoscale materials and devices with more conventional technology, and predictive modeling that will allow nanotechnology to be engineered reliably into useful applications and products. Nanotechnology can be expected to have an increasing impact on human lives and society at large. As we strive to use nanotechnology to improve human life through better healthcare, cleaner environment, and improved national security, we must also work to detect and assess the negative impacts that nanotechnology (or any new technology) might bring. We suggest that the conduct of science should be allowed to proceed unimpeded, so that we can fully understand and appreciate the rules of nature at the nanometer scale. That said, scientific pursuits that involve self-replication in synthetic systems, encryption, defense technology, or the enhancement of human intelligence should be reviewed. The development of new technology from fundamental science and the process of deciding what new technology is to be created for what purpose are topics for reasoned debate among the general public as well as in the forums of scientific peer review and political decision making. Dr. Alton D. Romig, Jr., is currently Vice President, Nonproliferation and Assessments, at Sandia National Laboratories (Albuquerque, NM). His responsibilities include the leadership and management of the development and engineering activities that provide systems, science, technology, and expertise in support of national objectives to reduce the threat to the United States from proliferation of and use of weapons of mass destruction. Program areas include remote sensing, proliferation assessment, technology assessment, international security, physical security, and nuclear/chemical/biological nonproliferation and counterintelligence. Dr. Romig is a member of the National Academy of Engineering and is active on a number of National Academy of Engineering/National Research Council Committees and Boards. He is a Fellow of the American Association for the Advancement of Science (AAAS) and member of Science, Engineering and Public Policy Committee and TMS (Fellow Class of 2005) (The Metals, Minerals and Materials Society).

Grain boundary cracking

A chronological summary is given of the various types of grain boundary fracture found in metals. In each case, there is an impurity that adsorbs at the new (fracture) surface being formed. For the case of Fe-P alloys, a quantitative argument can show that adsorption of phosphorous on the free surface greatly reduces the barrier to void nucleation compared to that in the absence of phosphorous. The same or larger reduction would appear for any other element, which adsorbs more strongly than phosphorous and displaces it at the surface. Such an argument is shown to explain a great many cases of dimpled grain boundary fracture in strong alloys undergoing creep or hydrogen attack. The reduction in surface energy can also lead to a smooth grain boundary fracture (no void nucleation), in which diffusion of solute to the new surface limits crack growth. Numerous examples of this are also discussed. Dr. Shewmon studied metallurgical engineering at the University of Illinois (B.S. 1952) and Carnegie Institute of Technology (Ph.D. 1955). His first job was at the Westinghouse Research Laboratory, where he studied thermal diffusion in alloys and surface diffusion. In 1958, he moved to the Carnegie Institute of Technology, where he served as a professor until 1967. The text “Diffusion in Solids” was published in 1963. An NSF Fellowship was used to study at Professor C. Wagner’s Max Planck Institute (Goettingen, Germany) in 1963. From 1968 to 1973, he was at Argonne National Laboratory, serving successively as Associate Director of the Metallurgy Division, Associate Director of the EBR-2 Project, and Director of the Materials Science Division. The text “Transformations in Metals” was published in 1969. Materials behavior in fast breeder reactors was the main theme of his work during this period. He was the director of the Division of Materials Research at the National Science Foundation from 1973 to 1975. From 1975 to 1993, he was Professor at Ohio State University in the Department of Metallurgical Engineering (later Materials Science and Engineering), serving as Chairman from 1975 to 1983. Research interests during this period were hard particle erosion and hydrogen-induced cracking of steel (“hydrogen attack”). From 1977 to 1993 he served on the Advisory Committee on Reactor Safety for the United States Nuclear Regulations Committee, serving as Chair for three of those years. Dr. Shewmon was elected to the National Academy of Engineering in 1979 and has been awarded the standing of Fellow in TMS, ASM, ANS, and AAAS. He has received several outstanding paper awards (Noble-AIME, Raymond—TMS, Mathewson—TMS, and Howe—ASM). He received the Distinguished Alumnus Award of the University of Illinois in 1981 and a Humboldt Foundation Senior Scientist Prize in 1984. The Edward DeMille Campbell Memorial Lecture was established in 1926 as an annual lecture in memory of and in recognition of the outstanding scientific contributions to the metallurgical profession by a distinguished educator who was blind for all but two years of his professional life. It recognizes demonstrated ability in metallurgical science and engineering.     

Deformation and fracture in martensitic carbon steels tempered at low temperatures

This article reviews the strengthening and fracture mechanisms that operate in carbon and low-alloy carbon steels with martensitic microstructures tempered at low temperatures, between 150 °C and 200 °C. The carbon-dependent strength of low-temperature-tempered (LTT) martensite is shown to be a function of the dynamic strain hardening of the dislocation and transition carbide substructure of martensite crystals. In steels containing up to 0.5 mass pct carbon, fracture occurs by ductile mechanisms of microvoid formation at dispersions of second-phase particles in the matrix of the strain-hardened tempered martensite. Steels containing more than 0.5 mass pct carbon with LTT martensitic microstructures are highly susceptible to brittle intergranular fracture at prior austenite grain boundaries. The mechanisms of the intergranular fracture are discussed, and approaches that have evolved to minimize such fracture and to utilize the high strength of high-carbon hardened steels are described.

Why materials science and engineering is good for metallurgy

Metallurgy/materials education will continue to evolve to encompass, in an intellectually unified way, the full range of structural and functional materials. Computation, information, and other advanced sciences and technologies will assume increasing roles in materials education, as will distance and continuing education. The advantages of the changes will be many … to the graduates, to emerging industries, and to the traditional metallurgical industries seeking productive, creative young engineers as employees. The need for continuing change in our metallurgy/materials departments is now no less if we are to attract the best young people into our field in the numbers needed and to best serve the needs of industry.
