根据固体与分子经验电子理论［１］的ＢＬＤ方法，建立了常用合金元素在马氏体中的价电子结构；利用Ｃ－Ｍｅ偏聚结构单元的ｎＡ值及其共价键络上的电子对分布，研究了马氏体价电子结构对回火转变的影响以及对马氏体力学性能的影响；并通过对热处理后的试样进行的透射电镜及能谱分析，验证了固相合金中Ｃ－Ｍｅ偏聚理论［２］．
The valence electron structures of common alloying elements in martensite are established according to the BLD method of solid and molecule empirical electron theory [1]. By using the nA value of C-Me segregating unit and the electron pair Distribution, the effect of the martensitic electronic structure on the tempering transformation and the effect on the mechanical properties of the martensite were investigated. The heat-treated samples were analyzed by transmission electron microscopy and energy dispersive spectroscopy to verify that the C -Me segregation theory [2].
