Nanopore Formation at the Junctions of the Polycrystal Intergranular Boundary Under Plastic Deformation

Abstract

The article is devoted to the study of the mechanism of nanopore formation in the junctions of polycrystal grains under the plastic deformation of a polycrystal due to the conservative sliding of lattice dislocations. A mechanism for the formation of a stress concentrator at the junction of the polycrystal grain boundaries is proposed. The possibility of relaxation of the stress state due to the formation of a junction nanopore is considered in the paper. --//-- This is an open-access article Suchikova, Y., Kovachov, S., Lazarenko, A., Bohdanov, I. and Popov, A.
