Abstract

The bronze processed multifilamentary Nb/sub 3/Sn superconducting wires with Cu-20 wt.% Nb composite reinforcement, which exhibited the high yield stress even after a typical heat treatment of about 700/spl deg/C for 8 days, have been fabricated. The strain effects on the critical current of the Nb/sub 3/Sn 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.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
