Possible methods of plasticity change in a superconducting transition

Translated from Zh. Eksp. Teor. Fiz., Pis'ma Red.; 17: No. 12, Dynamic mechanisms of weakening in N--S transitions, due to the decrease of electron dragging of dislocations, and quasistatic mechanisms due to the inhomogeneity of the dislocation structure, are discussed. (auth)
