应用固体与分子经验电子理论对中锰钢（１．２％Ｃ，８％Ｍｎ）奥氏体的价电子结构进行的计算表明，有Ｃ－Ｍｎ原子的偏聚；用ＴＥＭ组织观察和能谱分析发现奥氏体中有锰元素的偏聚；在ＴＥＭ薄膜原位动态拉伸变形试验中观察到应变诱发马氏体的形核与长大及高密度位错产生的过程；能谱分析发现马氏体相变区锰含量较低。从而提出应变诱发马氏体相变强化与高密度位错强化的双重作用是中锰钢加工硬化的主要机制
Calculations of the valence electron structures of austenite in medium manganese steel (1.2% C, 8% Mn) using the empirical electron theory of solids and molecules show the segregation of C-Mn atoms; TEM observation and energy spectrum The segregation of Mn in austenite was found by analysis. The nucleation and growth of strain-induced martensite and the generation of high-density dislocation were observed in in-situ dynamic tensile deformation test of TEM film. Martensite phase transition zone lower manganese content. It is proposed that the dual effect of strain-induced martensitic transformation strengthening and high-density dislocation strengthening is the main mechanism of work hardening of medium manganese steel
