The enhancement of the superconducting transition temperature T/sub c/ of tin by 100%, of bismuth-thallium by 32%, and of bismuth-lead by 22% due to plastic deformation is reported. It is found that the transition to the superconducting state is sharp. The resistivity rho and the critical field H/sub c/(0) are greatly affected. The electronic specific heat coefficient ..gamma.., the Debye temperature theta/sub D/, the density of states at the Fermi surface N(0), and the coupling constant lambda are computed for the undeformed and the deformed states. These parameters are also greatly affected by plastic deformation. The enhancement of T/sub c/ can be attributed to changes in theta/sub D/ and ..gamma...
