摘要： 以Fe-Mn-C系合金奥氏体为例,分析了Me(合金元素)对Fe-Me-C合金奥氏体价电子结构的影响.结果表明,Me含量可影响Fe-Me-C奥氏体中各类原子组态的几率,亦即影响各类晶胞的相对数量;将计算C原子分数的公式改为Ac=100C/12\[((100-C-m)/56)+C/12+m/M],即可在计算Fe-Me-C奥氏体含C-Me晶胞的晶格常数时计入Me的影响;Me主要通过影响含C Me晶胞的晶格常数、等同键数和各类晶胞的权重而影响合金固溶体的价电子结构.

Abstract: This paper deals with the analysis of effect of Me (alloying element) on valence electron structure of Fe-Me-C alloyed austenite taking Fe-Mn-C austenite for example.The results show that Me content can affect the occurence probability of all kinds of atomic configurations,i.e.the relative amount of cells.By modifying the equation calculating the atom fraction of carbon into Ac=100C/12\[((100-C-m)/56) + C/12 + m/M],the effect of Me on crystal parameter can be characterized.Me influences the valence electron structure of alloying solid solution principally th rough its effects on crystal parameter,iso-bond number and right of cells.

Key words: Fe-Me-Calloy, valence electron structure, austenite
