THERMODYNAMICS OF SUBSTRUCTURE TRANSFORMATIONS UNDER PLASTIC-DEFORMATION OF METALS AND ALLOYS

The paper is devoted to behavior of the energy stored in deformed meta ls and alloys. The study is based on the well-known theoretical approa ches and on the electron microscopy data obtained by the authors durin g investigation of the deformed Cu-Al and Cu-Mn f.c.c. alloys. Influen ce of the solid solution hardening value on the mechanisms of dislocat ion substructure evolution was studied. The accumulated energy for the substructure being formed at plastic deformation was evaluated. Ways of improvement of such evaluations were considered. (C) 1997 Elsevier Science S.A.
