Emission Transfer of Interstitial Atoms Under Shock Deformation of a Metal Surface

Abstract

The process of anomalous transfer of interstitial atoms during impact deformation of the crystal surface is described theoretically. As shown that surface impact leads to the formation of a wave of inhomogeneous atomic displacements in the medium, which propagates from the surface into the depth of the crystal. The formation of a deformation wave leads to a change in the interatomic distance at the wave front and a change in the potential energy for interstitial atoms. Interstitial atoms at the front of the deformation wave receive an additional impulse, which leads to an increase in their kinetic energy and contributes their movement deep into the crystal.
