两种方法分析高锰钢和18-8不锈钢加工硬化行为的对比
Comparison of Work Hardening Behaviors of 18-8 Stainless Steel and Hadfield Steel by Two Methods
摘 要
对高锰钢和18-8不锈钢进行了室温拉伸试验,通过Hollomon法和Crussard-Jaoul法分析了高锰钢和18-8不锈钢的加工硬化行为.结果表明:Crussard-Jaoul法比Hollomon法能更好地分析高锰钢和18-8不锈钢加工硬化行为的特点和机制;18-8不锈钢以位错滑移为塑性变形机制,高锰钢在低应变阶段(e≤0.07)也以位错滑移为主要的塑性变形机制,但当真应变超过0.07时,则以孪生为主要的变形机制;正是孪晶的产生导致了高锰钢和18-8不锈钢加工硬化行为的显著差异.

Abstract
The tensile tests for both hadfield steel and 18-8 stainless steel were carried out at room temperature.The work hardening behaviors of both steels were analyzed by Hollomon method and Crussard-Jaoul method.The results show that the Crussard-Jaoul method could better describe and characterize the characteristics (of work hardening behavior) and mechanism of 18-8 stainless steel and hadfield steel as compared with Hollomon method.The deformation mechanism of 18-8 stainless steel was dislocation slip.The deformation mechanism of hadfield steel was also dislocation slip when the strustrain was below 0.07,but twinning would occur when the strustrain was over 0.07.It was the occurrence of twinning that led to unusual work hardening at large strain in hadfield steel and 18-8 stainless steel.
