摘要
通过对碳锰结构钢奥氏体中各类晶胞出现概率的计算表明在分析钢相变过程中不应忽视Fe-Mn晶胞所起的作用。并利用EET理论计算出该晶胞的价电子结构,结果表明由最强键和次强键可以形成一种八面体结构。该结构对相变及其他性能都具有重要的影响作用。同时还提出了碳锰结构钢奥氏体中C-Mn偏聚区原子分布及晶胞结合模型。
The probability of different unit-cell in austenite of Carbon-Manganese structural steel was calculated. The results show that Fe-Mn unit-cell is so important that its influence on phase transformation should not be ignored. The valence electron structure of Fe-Mn unit-cell is studied by EET(The Empirical Electron Theory of Solids and Molecules). An octahedron made up with the strongest and substrongest keys is formed in the cell,which will effect on the phase transformation and other properties of steel. Meanwhile,the atoms distribution model of C-Mn segregation area in austenite of the Carbon-Manganese structural steel is proposed.
