Abstract

The mechanisms of alternating severe plastic deformation (SPD) of polycrystalline foils of high-purity aluminum glued on hard bulk samples are studied on a mesoscale. It is shown that the SPD mechanisms and its self-organization on a mesoscale are controlled by the field of maximal shear stresses and rotational strain modes caused by the couple-forces. The effect of the degree of nonequilibrity of the material under SPD on the deformation mechanism is analyzed in terms of the nonequilibrium thermodynamics of local structure-phase transformations in zones of hydrostatic tension.

N2 - The mechanisms of alternating severe plastic deformation (SPD) of polycrystalline foils of high-purity aluminum glued on hard bulk samples are studied on a mesoscale. It is shown that the SPD mechanisms and its self-organization on a mesoscale are controlled by the field of maximal shear stresses and rotational strain modes caused by the couple-forces. The effect of the degree of nonequilibrity of the material under SPD on the deformation mechanism is analyzed in terms of the nonequilibrium thermodynamics of local structure-phase transformations in zones of hydrostatic tension.
