Influence of Pressure on the Processes of Formation and Evolution of the Nanostructure in Plastically Deformed Metals and Alloys

Abstract

The role of volume changes on the structural rearrangements of dislocation pileups accompanied by the formation of the intercrystallite boundaries, pores, and microcracks upon the plastic deformation of materials is analyzed. The results of this analysis are applied to the study of the microscopic mechanisms of the effect of pressure on processes of the formation and fracture of the nanostructure of metals and alloys.
