Anisotropy migration of self-point defects in dislocation stress fields in BCC Fe and FCC Cu
چکیده انگلیسی

Spatial dependence of the interaction energies of self-point defects (vacancies and self interstitial atoms in stable, metastable and saddle point configurations) with edge dislocations in slip systems 〈1 1 1〉{1 1 0} and 〈1 0 0〉{1 0 0} in BCC Fe and 〈1 1 0〉{1 1 1} in FCC Cu was calculated using the anisotropic theory of elasticity and molecular statics (hybrid method). The migration pathways of vacancies and SIA (〈1 1 0〉 dumbbell in Fe and 〈1 0 0〉 dumbbell in Cu) along which the migration of the defects with the lowest energy barriers were defined in the presence of the dislocation stress fields. These pathways are significantly different in the stress fields of dislocations.
