摘　　要：运用价电子理论,从统计分布和元素间的互作用两个角度考虑,提出了新参数结构单元分布因子来研究奥氏体中八面体结构单元的分布几率,并结合结构单元的能量讨论了锰钢中马氏体的转变,从而建立了微观结构与宏观性能的联系.By using valenceelectron theory and taking into consideration of both the statistical distribution and inter element actions, a new parameterdistribution factor of structural unit is advanced in this paper to investigate the distributional probability of an octahedron structural unit in austenite. Further, the transformation of martensite in Mn steel is discussed in connection with the energy of structural unit so that the relationship between microscopic structure and macroscopic properties is set up.
