Abstract

A new approach to magnet fabrication, react, wind and sinter (RWS), has been proposed for Bi₂Sr₂CaCu₂O_X (Bi2212), magnets. In this process, the conventional Bi2212 heat treatment is split into two portions, and the magnet is wound between these heat treatments. Here we report results on the RWS "split melt process". Significant increases in I_c are obtained in Bi2212 round wires compared to standard melt processing. Strain effect measurements, using the Lorentz force, indicate that RWS wires have similar mechanical performance as wind and react wires. Effects of the split melt temperature on the electromechanical properties are also reported. These results show that split melt processing and RWS magnet fabrication are viable approaches for Bi2212 conductors and magnets.
