Abstract
Superconducting Pb–Sb alloys of nonequilibrium concentration are studied. The effect of decomposition of a supersaturated solid solution on low-temperature plastic properties (yield strength) of the alloys and on some of their superconducting parameters (second critical magnetic field, residual magnetic inductance) is investigated. The evolution of an imperfect structure under different heat treatments is studied as well as the interaction of dislocations and magnetic flux vortices with structural components.
