摘要
锰钢奥氏体的价电子结构和原子组态计算表明，在含Ｃ、Ｍｎ晶胞中，Ｃ－Ｍｎ键的共用电子对数最多，异类原子间的结合力大于同类原子间的结合力；一个晶胞含一个锰原子的几率最大。通过价电子结构的主要数据，从微观结构方面揭示了锰钢奥氏体的成分偏聚、组织稳定性、塑韧性和加工硬化及其变化的本质。
This paper deals with the relationship between valence electron structure of austenite in manganese steels and its microstructure and properties. Through the calculations of valence electron structure and atomic configuration of the austenite in manganese steels, it is shown that the number of common electron pair of the C Mn bond is the largest in the cell with C, Mn, and the bond strength between heter atoms is higher than that between iso atoms. For a single cell, it is most likely to contain Mn atom. Meanwhile, by using of the principal data of valence electron structure, the component segregation, structural stability, ductility and toughness and work hardening of the austenite were revealed on the microstructure level.
