| 摘 要： | 本文用计算机再次模拟了FCC:BCC部分共格界面结构。发现失配位错并不是FCC:BCC部分共格界面不可缺少的结构要素,界面上两个方向台阶存在可以使共格区增多和两相界面能降低,对R-A结构模型进行了补充和修正。

| Abstract: | The structure of FCC: BCC boundary, which is expected to be partially coherent and to be defined by Nishiyama-Wasserman orientation relationship,is resimulated by computer. The results show that the misfit dislocation is not the necessary structural element on the partially coherent FCC:BCC boundary,and introducing the structural ledges in two directions brings about an increase in the interfacial coherency and a decrease in the interfacial energy. A structural model of FCC:BCC partially coherent interface is made,which replenishes with and amends the R-A model. |
