摘要
综合分析了国外第3代粉末高温合金的化学成分、显微组织和点阵常数,总结出新型涡轮盘用高性能粉末高温合金的研发趋势,重点介绍了作者课题组与钢铁研究总院合作在国内率先进行我国新型第3代高性能粉末高温合金的初期研究工作与成果,并提出了研制高性能粉末高温合金的重点研究方向。
The chemical compositions, microstructure and lattice parameters of the 3rd generation powder metallurgy (P/M) superalloys abroad are comprehensive analyzed and the development tendency of new type high-performance turbine disk P/M superalloy is obtained by the summary of this process. The primary research work and achievements of our country's new type 3rd generation high-performance P/M superalloy which has been done by the initial cooperation work of the present authors' group and CISRI are introduced with emphasis. The important research orientation is also present in developing high-performance P/M superalloys.
