Features of structural transformation of disperse-strengthened vanadium alloys under conditions of deformation by torsion under pressure and tension at room temperature
A comparative study of the features of microstructure transformation in disperse strengthened vanadium alloys of the V-Me(Cr, W)-Zr system under conditions of deformation by torsion under pressure and tension at room temperature was carried out. It was found that suppression of dislocational plasticity in the high-strength state favors the formation of an anisotropic submicrocrystalline structure both during torsional deformation and in the region of strain localization in the case of tension at room temperature. It is shown that one of the main mechanisms of crystal fragmentation under these conditions is a dislocation-disclination mechanism, for the realization of which structural states with nonzero values of the curvature rotor or a high continual density of disclinations are necessary.
