摘　　要：为满足先进航空发动机高压涡轮盘等热端部件的使用要求,需要研制更高性能的第四代粉末高温合金,其标志是最高使用温度要达到815℃。概述了最近10年来美国和英国第四代粉末高温合金的研究进展情况。重点介绍了美国高Ta含Hf的ME501合金和高W高Ta含Hf的TSNA-1合金,英国的高Co高Ta合金、高Ta低成本合金和高Nb的RRHT系合金的成分设计特点、组织及其稳定性、力学性能及抗氧化性。In order to meet the service requirements of advanced aero-engines,especially hot-end components such as high-pressure turbine disks,it is extremely necessary to develop higher-performance fourth generation powder metallurgy superalloys.The characteristic of these materials is the achievement of a maximum service temperature of 815℃.In this review,the fourth generation PM superalloys developed by the United States and the United Kingdom in the past decade has been introduced.The main content is focused on ME501 and TSNA-1 alloys developed in the US,and novel alloys developed in the UK(including high-Co and Ta content alloys,low-cost alloys with high-Ta content and a series of RRHT alloys with high-Nb content).The design characteristics of the chemical composition,microstructure stability,mechanical properties and oxidation resistance of these alloys are concerned in this paper.
