TiAl金属间化合物与42CrMo"三体"摩擦焊接头的热机械处理

<title>ermal Mechanical Process of ' 3 Body' Friction Welded Joint of TiAl Intermetallic Compound and 42CrMo

在对"三体"摩擦焊热机械处理(TMP)的作用原理进行理论分析的基础上,研究了接头的组织变化和动态再结晶规律,从而形成了以摩擦焊热力耦合与焊后热处理制度复合的TMP模式。

<abstract> the basis of theoretical analysis of the principle of thermal mechanical process (TMP) of ' 3 body' friction welding, the regulation of structure change and dynamic recrystallization of joint are studied, and the TMP pattern of combining the thermody namic coupling of friction welding with post-welded heat treatment system is formed.
