Abstract
Abstract—The migration energies of a vacancy and an interstitial atom in the ordered CuPt alloy are calculated using molecular dynamics simulation. A high interstitial atom migration anisotropy is detected: as a rule, an interstitial atom migrates along the (111) planes containing copper atoms. A similar anisotropy is also observed for the vacancy migration during elastic tensions along these planes.
