Stress-induced enhancement of T c in bronze-processed V3Ge

Compressive stresses arising from differential contraction of the bronze matrix were found to cause an increase in the critical temperature, Tc, of bronze-processed V3Ge. This unusual behavior for an A-15 compound is in qualitative agreement with Testardi’s theory, although the enhancement of Tc does not increase parabolically with strain and saturates at strains of ∼0.5%.
