摘要
采用摩擦焊后水淬和空冷的方法研究了２０ＣｒＭｏ＋３５ＣｒＭｏ摩擦焊接头热影响区晶粒状态及其影响因素。研究结果表明，摩擦焊接头近缝区处于动态再结晶状态。分析了其晶粒尺寸与Ｚｅｎｅｒ－Ｈｏｌｏｍｏｎ因子的关系，指出强工艺规范可使晶粒细化，使焊缝韧性提高。
This paper has studied the grain state of friction welded joint and its influence factorsThe results show that the region near the weld is in the state of dynamic recrystallization after welding followed by air coolingThe relationship between the grain size and ZenerHollomon factor has been analyzedIn addition,welding in intensive specification is favourable to obtaining finer grain and higher toughness of weld
