| 摘 要： | 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。

| Abstract: | The Valence electron structures of bainite and its original aus-tenite phase of Fe-C-Cr-Si alloy are devaloped by the empirical electron theory of solid and molecules by S、H、Yu. According to the short range segregation due to the valence electron structure, the effect on the C-curVe by elements Cr、 Si during isothermal transformation of the over cooling austenite is discussed. Since the behaviour of elements Cr and Si during the isothermal Transformation depends on the segregation force of C-Cr、 C-Si, the formation of C-curve of Fc-C-Cr-Si alloy is traced back to the valence electron structures of these alloy phase. |
