Influence of High Hydrostatic Pressure on the Vibrational Spectrum of an Edge Dislocation and Its Dynamic Interaction with Point Defects

Abstract

The slip of a single edge dislocation in an elastic field of point defects chaotically distributed over a crystal with allowance for a high hydrostatic pressure has been studied theoretically. The numerical estima tions have demonstrated that hydrostatic compression of some metals and alloys increases the dislocation drag force by point defects in them by several tens of percent.
