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.  相似文献

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.

Materials science and engineering has been emerging as a unique academic discipline during the last decade and a half. The role of chemical metallurgy in this emerging field is not well defined, yet it has played an important historical role in the intellectual development of the discipline of metallurgical engineering in terms of teaching, research, and technological appli-cations. In this lecture, I have attempted to define the role of chemical metallurgy in this emerg-ing field and, moreover, to propose using the broader term “chemical processing of material” instead of chemical metallurgy. The role is to educate materials scientists and engineers at the baccalaureate degree level as well as the graduate degree level. I believe that if materials sci-entists and engineers have a good grasp of the principles of chemical processing of materials, they will be in an excellent position to tackle many of the challenging and important problems facing us in the materials field. I have also given in this lecture three diverse examples of materials problems that have been studied using the basic principles of chemical processing of materials. These examples are used to demonstrate that the tools of chemical metallurgy can be used effectively to study many contemporary materials science and engineering problems.  相似文献

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.

Titanium alloys in total joint replacement--a materials science perspective   总被引:1,自引:0,他引:1  
Increased use of titanium alloys as biomaterials is occurring due to their lower modulus, superior biocompatibility and enhanced corrosion resistance when compared to more conventional stainless steels and cobalt-based alloys. These attractive properties were a driving force for the early introduction of alpha (cpTi) and alpha + beta (Ti-6A1-4V) alloys as well as for the more recent development of new Ti-alloy compositions and orthopaedic metastable beta titanium alloys. The later possess enhanced biocompatibility, reduced elastic modulus, and superior strain-controlled and notch fatigue resistance. However, the poor shear strength and wear resistance of titanium alloys have nevertheless limited their biomedical use. Although the wear resistance of beta-Ti alloys has shown some improvement when compared to alpha + beta alloys, the ultimate utility of orthopaedic titanium alloys as wear components will require a more complete fundamental understanding of the wear mechanisms involved. This review examines current information on the physical and mechanical characteristics of titanium alloys used in artifical joint replacement prostheses, with a special focus on those issues associated with the long-term prosthetic requirements, e.g., fatigue and wear.  相似文献
