20世纪中、后期的粉末冶金新技术和新材料(1)——新工艺开发的回顾

New P/M technologies and materials developed in late-20th century:(1)——Review of new techniques development

介绍了20世纪中、后期开发的一些粉末冶金新工艺的历史沿革和发展现状,包括粉末锻造、热等静压、快速凝固、燃烧合成、喷射成形、机械合金化、粉末注射成形等。由这些新工艺创造出来的一系列粉末冶金新材料,包括粉末冶金高速钢、稀土永磁材料、粉末冶金高温合金、粉末冶金高强度铝合金、纳米粉末材料和非晶态合金粉末材料等,将在下期连续刊出。

The origin and development status of some important new techniques emerged in the mid and late of the 20th century were introduced. These technologies include powder forging, hot isostatic pressing, rapid solidification, combustion synthesis, spray forming, mechanical alloying, powder injection molding, etc. And some important new P/M materials developed by utilizing the above new technologies are to be introduced in next isue of the present periodical.
