Abstract:

Based on the results of the thermodynamic analysis of a number of experimental data, and in the light of the Kaibyshev-Valiev discovery, the possibility of periodic formation of a liquid-like state in the nanoregions of extremely "non-equilibrium" grain boundaries and in other structural defect regions in metallic polycrystals during their superplastic deformation and intense plastic deformation is considered. It is also considered important differences between the liquid-like state and the glass-like (amorphous) state.
