Comparison of mechanisms of plasticity enhancement at the superconducting transition

The mechanisms of the plasticity enhancement at the N-S transition are considered, based on a comparison of the dependence of this effect on the concentration of defects limiting the dislocation mobility, which, as is shown, is different for competing dynamic models. A method is suggested for determining the role of quasistatic effects, arising due to the inhomogeneity of the dislocation structure of superconductors, in the plasticity enhancement at the N-S transition.
