Abstract
AT c increase up to 0.5 K was produced by plastic deformation at low temperatures of Nb and V in a solid pressure cell. Annealing experiments on these materials show that the increase ofT c disappears below 100 K while the change of the residual resistance removes only partially up to room temperature. This can be explained by tensile stress producing regions with enhancedT c .
