Influence of a change in the plasticity of metals and alloys during a superconducting transition on the yield point above <i>Tc</i>

The influence of prestraining at a temperature below Tc of superconducting lead and lead-bismuth alloy specimens in the normal and superconducting states and under a multiple repetition of the superconducting transition on the straining stress above and below Tc is studied. It is discovered that prestrain with multiple n→s transitions results in an additional rise in the yield point.
