美国爱达荷大学工业材料技术公司和Battelle Pacific西北国家实验室的D.K.Mukhopadhyay及其合作者在一个关于“开发核聚变反应堆用氧化物弥散强化铁素体钢”的研究计划报告中论述了当前开发的情况。他们用机械合金化法,然后通过热等静压和热旋锻合成以Fe-(5-13.5)Cr-2W-0.5Ti-0.25Y_2O_3为基的氧化物弥散强化(ODS)合金。该合金与合添加钼的高激活合金市场提供的MA957合金有明显的不同,含较低激活性的元素钨。低激活性意味着放射性半衰期缩短,使用后废弃物处理非常容易。在研究计划中,确
DK Mukhopadhyay and his collaborators at the Industrial Materials Technology Company of the University of Idaho and Northwest National Laboratory in Battelle Pacific discussed the current developments in a research project report on “Development of oxide-dispersion-strengthened ferritic steels for nuclear fusion reactors” Case. They used a mechanical alloying method and then synthesized an oxide dispersion strengthened (ODS) alloy based on Fe- (5-13.5) Cr-2W-0.5Ti-0.25Y_2O_3 by hot isostatic pressing and hot swaging. The alloy is significantly different from the MA957 alloy available in the market for high-activation alloys with molybdenum added, with less active elemental tungsten. Low activation means shorter radioactive half-lives and easier disposal of waste after use. In the research plan, indeed
