用分子的动力学方法,我们构造了相应于的二个纽结模型 < 100 ){ 010 } 并且(100 ){ 011 } 在身体的边脱臼(版本) 集中了立方(电子消息传输方式) Fe。性变态的几何结构在脱臼核心区域取决于边脱臼的类型和原子地点的结构的精力,这被发现。形成精力,迁居精力和在版本的不同类型的性变态的宽度是计算的。结果显示出纽结的那形成和移植在 < 100 ){ 010 } 边脱臼是困难的。< 100 ){ 011 } 首先通过纽结成核的边脱臼行动,而非纽结移植。
Using the molecular dynamics method, we have constructed two kink models corresponding to the (100){010} and (100){011} edge dislocations (EDs) in body centred cubic (bcc) Fe. It is found that the geometric structure of a kink depends on the type of edge dislocation and the structural energies of the atoms sites in the dislocation core region. The formation energies, migration energies and widths of the kinks in different types of EOs are calculated. The results show that formation and migration of the kink in the (100){010} edge dislocation are difficult. The (100){011} edge dislocation moves primarily through kink nucleation, rather than kink migration.
