Thermodynamics of substructure transformations under plastic deformation of metals and alloys

The paper is devoted to behavior of the energy stored in deformed metals and alloys. The study is based on the well-known theoretical approaches and on the electron microscopy data obtained by the authors during investigation of the deformed Cu-Al and Cu-Mn f.c.c. alloys. Influence of the solid solution hardening value on the mechanisms of dislocation 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.
