摘要	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 EDs 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.
