摘要
瞬间液相(transient liquid phase,TLP)连接是目前用于连接镍基高温合金的一种优化技术,而连接后热处理(postbond heat treatment,PBHT)是对连接后的接头进行的热处理工艺,本文对TLP连接中热循环对镍基高温合金母材组织性能的不利影响和TLP连接后接头存在的有害问题进行归纳汇总,对PBHT工艺的机理、种类及研究现状等进行详细分析,对其适用体系和效果进行系统评述。针对未来的PBHT工艺研究,建议继续向多级多道精准热处理的方向发展,并探索TLPB-PBHT一体化工艺。
Transient liquid phase(TLP)bonding is an optimised bonding process that joins nickel-based superalloys.The post-bond heat treatment(PBHT)refers to a heat treatment process for the joint after the connection.This article summarizes the adverse effects of TLP thermal cycling on the tissue properties of nickel-based superalloys and the harmful phase problems of joints after TLP joining.The article explains the mechanism,types and current status of the PBHT process,analyses and discusses the systems and effects of the PBHT process where it is applicable.Finally,the development prospects and future research directions are presented.For future PBHT process research,it is recommended to continue to develop in the direction of multi-level and multi-pass precision heat treatment,and explore the TLPB-PBHT integrated process.
