摘　　要：近年来我国对高性能航空发动机的需求越来越迫切,随之涡轮盘用合金服役环境也越来越苛刻,耐700℃以上的GH4065、GH4720Li、GH4068和GH4151等一系列涡轮盘用铸锻合金被广泛研究、制备或使用。为了促进这类合金的发展和综合性能提升,本文从合金种类、均匀化处理工艺、铸锭开坯、盘件制备和组织性能调控等方面综述了我国涡轮盘用铸锻难变形合金的热加工研究现状,凝练出这类合金在研究制备过程中的短板问题,并对未来的工作方向进行了展望,借此促进涡轮盘用铸锻难变形高温合金的发展和工艺稳定性的提升。In recent years,the demand for high-performance aero-engines has become crucial in China,and the service environment of turbine disk alloy becomes increasingly severe.A series of high resistant cast & wrought superalloys for turbine disks,such as GH4065,GH4720Li,GH4068,and GH4151,with working temperatures> 700℃,have been studied,produced,and applied widely.The current studies on cast & wrought alloys for turbine disks in China were summarized under the categories of homogenization treatment,cogging,disk forging,and microstructure and property regulation to promote the development of these superalloys and improve their comprehensive properties.The difficulties encountered during the research and preparation of these hard-to-deform superalloys and explored the alloys’ potential development trend were outlined.The review would improve the production stability of the disk superalloys and promote their development.
