Computer simulation of creation and motion of dislocations in aluminum small single crystals

Abstract

Complete and dissociated edge dislocations were created near the center of the surface ( 01) of aluminum small crystals whose surfaces are (111), ( ), ( 01), (10 ), ( 2 ) and (1 1). Moleculer dynamics with N-body embedded atom potentials were used. Higher stress is needed to create a complete edge dislocations than to create a dissociated dislocation. Molecular dynamics is used.
