摘要
A general approach to the description of the basic laws of structural and phase solid state transformations occurring upon severe plastic deformation (SPD) is proposed within the concept of the appearance of additional channels for the dissipation of mechanical energy supplied to the solid state. It is shown that the active involvement of cyclic processes of low-temperature dynamic recrystallization and of the << crystal double left right arrow amorphous state >> phase transformations in combination with additional thermal effects under the conditions of insufficient efficiency of dislocation and disclination accommodation processes can consistently explain almost all the main experimental results obtained to date for SPD.
