Enhancement of the Superconducting Transition Temperatures of Ti–Mo (5, 7 at.%) Alloys by Mechanical Deformation

Abstract

Low-temperature calorimetric measurements have shown that severe mechanical deformation of Ti–Mo (5 and 7 at. %) alloys, although it has little influence on either the density of states or the Debye temperature, significantly enhances the superconducting transition temperature. The net effect of the deformation is thus to distort the phonon spectrum in such a way as to favor the superconducting electron coupling.
