利用余瑞璜的“固体与分子经验电子理论”建立了Fe-C-Cr-Si合金贝氏体及母相奥氏体的价电子结构。从价电子结构导致的短程偏聚讨论了过冷奥氏体等温转变时Cr、Si对C-曲线的影响。由于Cr、Si在等温转变时的行为取决于C-Cr、C-Si偏聚力的大小,因此Fe-C-Cr-Si合金相变动力学C-曲线的形成便追溯到合金相的价电子结构。
The valence electron structure of bainite and parent austenite of Fe-C-Cr-Si alloy was established by using the “theory of solid and molecule empirical electron theory” by Yu Ruihuang. The effect of Cr and Si on C-curve during the isothermal transformation of undercooled austenite was discussed. The behavior of Cr and Si during isothermal transformation depends on the C-Cr and C-Si cohesion, so the formation of C-curve of phase transformation of Fe-C-Cr-Si alloy dates back to the valence electron structure.
