摘　　要：概述了国内外耐600℃及以上高温钛合金的研究现状,在总结英国IMI834、美国Ti-1100、俄罗斯BT36、中国Ti60、TG6、Ti600、Ti65、Ti750等合金组成及性能的基础上,指出了制约高温钛合金发展的主要瓶颈,并针对目前的研究现状,提出了一些可供借鉴的解决办法。从提高高温钛合金的热稳定性、热强性和高温蠕变强度的角度对制备Ti基复合材料、优化合金成分、优化热加工工艺调控组织、控制α2相的尺寸、数量、体积分数和形态等方面进行了未来展望,为高性能高温钛合金的研制提供了理论基础和参考作用。This paper reviews the development status of high-temperature titanium alloys resistant to600℃and above in domestic and foreign situations,and summarizes the composition and properties of IMI834 from UK,Ti-1100 from USA,BT36 from Russia and Ti60,TG6,Ti600,Ti65 and Ti750 from China.The main bottlenecks limiting the development of high-temperature titanium alloys are figured out,and some possible solutions are proposed for reference based on the current research status.In view of improving the thermal stability,thermal strength and high-temperature creeping strength of high-temperature titanium alloys,the future perspectives of preparing Ti-based composites,optimizing the alloy compositions and the thermal processing processes,controlling the size,number,volume fraction and morphology of theα_2 phase and protecting the high-temperature oxide coating are prospected.This paper provides a theoretical basis and reference for the development of high performance high temperature titanium alloys.
