Carbon dioxide reduction technologies: A synopsis of the symposium at TMS 2008

Common fuels—whether they are simple hydrocarbons or oxygenated hydrocarbons or carbohydrates—can be economically produced from the respective oxides of carbon and hydrogen by simple chemical reductions. These reactions are efficiently carried out by applying fundamentals of the reduction process. Dr. Neelameggham is also the JOM advisor from the Reactive Metals Committee of the TMS Light Metals Division.     

2010年中国钛工业发展报告

回顾了2010年中国钛工业的运行情况,介绍了中国钛工业的生产和进出口情况,分析了海绵钛和钛加工材的价格走势。2010年中国钛工业呈明显回升状态,海绵钛产能突破10万t,产量达到57770t,与2009年相比增长41．6％;钛加工材产量达到38323t,与2009年相比增长53．5％。2010年,中国化工、航空航天、冶金、真空制盐等行业用钛大幅增长,从而使中国钛制品的销售量达到创记录的35636t;特别是化工用钛量已近2万t,成为中国用钛的绝对第一大领域。应更好地把钛材的应用推广工作做好,迎来行业的更大发展。     

Effect of Annealing and Cold Work on Mechanical Properties of Beta III Titanium

Experiments have been carried out to study the effect of annealing and cold work (CW) on the mechanical properties of beta III Ti alloy. Material was annealed at different temperatures above the beta transformation temperature, and then cold drawn to about 53% area reduction. Cyclic tensile test was performed to study the evolution of mechanical properties and the recoverable strain during process. Results show that the effect of annealing and CW is closely related to the stress-induced martensite (SIM) phase transformation. Lower annealing temperature results in higher strength and recoverable strain, which is further increased by CW. A total recoverable strain of ~3.2% was obtained from the annealed and CW sample.
