Molecular dynamics investigation of behavior of grain boundaries under thermo-mechanical external impact

Abstract

Molecular dynamics simulation of behavior of grain boundaries in bicrystal under shear loading were carried out. A variety of metals was investigated. The possibility of movement of the grain boundary in a direction perpendicular to the applied load was shown. The dependencies of the velocity of grain boundaries on the sample temperature are analysed. Results obtained in this paper help to understand the features of development of plastic deformation in polycrystals under shear loading.
