Softening of Young's modulus and the occurence of the martensitic transformation were found to be strongly affected by the presence of relatively small amounts (0 to 4 at. %) of Ta, Ti or Zr with the largest effects occurring for Ti. Additions incorporating 2 at. % Ti in the Nb/sub 3/Sn causes Young's modulus to increase by a factor 2 at 10K and the transformation to be suppressed. Since Young's modulus also increases rapidly with strain, further measurements will be required to determine to what extent the stress state of Nb/sub 3/Sn incorporated in a bronze matrix is affected by ternary additions. 3 figures.
