【摘要】 本文用余瑞璜先生的“固体与分子经验电子理论”计算了工业牌号的50、50Cr、50CrV钢奥氏体的价电子结构,从原子杂化状态、共价键力大小的价电子深度,讨论了合金相的价电子结构对过冷奥氏体等温转变的影响,并结合60Si₂Mn钢奥氏体的价电子结构,讨论了碳化物形成元素Cr、V和非碳化物形成元素Si在相变中的行为与作用。键距差（BLD）分析的基础数据由余瑞璜先生提供。更多还原

【Abstract】 Based on the empirical electron theory of solids and molecules of prof .R.H.Yu,the valence electron structure of 50,50Cr and 50CrV austenite was established. The influence of atomic state and atomic bonds on the isothermal transformation of austenite was discussed, and the behavior on phase transformation of Cr, V and Si were as well. The basic data of BLD analysis was advanced by prof. R.H.Yu.更多还原
