Role of the deformation point defects in deformation hardening of materials with F.C.C. structure

Annotation

Change of the deformation point defects concentrations in process of plastic strain of metals with F.C.C. structure is investigated. It is shown that point defects provide connectivity of the substructural levels system and there of influence on work hardening.

Keywords

plastic strain; hardening; point defects; dislocations; fragments; boundaries
