Abstract
The deformational structure and the phase composition of binary and commercial aluminumcopper alloys produced using electroplastic deformation by rolling (EPDR) have been studied. It has been shown that structural transformation in the materials and changes in their hardness in the course of EPDR are governed by the initial state, which determines the distribution and the thermomechanical stability of a dislocation ensemble. It has been found that EPDR causes the dynamic deformation-induced aging of the aluminum-based supersaturated solid solution, which is accompanied by the precipitation of the strengthening θ phase in the Al-Cu alloy and the S phase in the D16 alloy.
