Abstract
The effects of interstitial hydrogen on the elastic softening, the martensitic transformation and the critical temperature of Nb₃Sn were studied. Using internal friction as a diagnostic tool, it was found that the martensitic transformation temperature is decreased with hydrogen and completely suppressed for ∼ 0.6 at %H. For these small hydrogen additions, the onset critical temperature is increased to ∼ 18.4K. For higher concentrations of hydrogen, Tc decreases as previously reported and softening of Young's modulus is almost entirely suppressed.
