This investigation of the degradation in the superconducting properties of Nb/sub 3/Sn conductors when subjected to mechanical strain can be divided into the following areas: (I) monofilamentary Nb/sub 3/Sn wires, (II) multifilamentary Nb/sub 3/Sn conductors and wires, (III) effects of additives to Nb/sub 3/Sn, (IV) mechanisms for degradation, and (V) construction of test facilities. Efforts to the present time have been concentrated in the investigation of T/sub c/, J/sub c/, and H/sub c2/ variations in monofilamentary wires. The most important finding in this study is that a Nb/sub 3/Sn composite wire can sustain an effective mechanical strain well beyond ''1%'' if a proper ratio of the matrix to the Nb core has been chosen.
