摘要：
The bronze processed multifilamentary Nb3Sn superconducting wires with Cu-20 wt.% Nb composite reinforcement, which exhibited the high yield stress even after a typical heat treatment of about 700 degrees C for 8 days, have been fabricated. The strain effects on the critical current of the Nb3Sn wires reinforced with CuNb composite were measured, and the estimation of residual strain was performed using a rule of mixtures. Good agreement is obtained between measured and calculated residual strain values.
