Abstract
The mechanical and electrical properties of Cu-Nb composites were investigated from the standpoint of reinforcement and stabilizing materials for a Nb3Sn wire. After annealing at 943K for 240 hours, Cu-15, 20 and 30wt%Nb composites had the 0.2% proof stress of 228, 246 and 26OMPa at room temperature, respectively. A bronze processed multifilamentary (Nb,Ti)3Sn wire with Cu-Nb reinforcing stabilizer was newly developed. The 0.2% proof stress at 4.2K of the Cu-Nb/(Nb,Ti)3Sn wire was noticeably improved and the value of 314MPa was obtained after the heat-treatment of (Nb,Ti)3Sn formation at 943K for 200 hours. The strain effect of the critical current for Cu-Nb/(Nb,Ti)3Sn were measured at 14T and 4.2K. The strain dependence of Ic/Icm of the Cu-Nb/(Nb,Ti)3Sn wire was nearly the same profile as the conventional wire. It was verified that the Cu-Nb/(Nb,Ti)3Sn wire has the performance enough for both mechanical and superconducting properties under an enormous electromagnetic force in high magnetic fields such as 15T or more.
