摘要：
Nb3Al superconductors have shown promising performance compared to Nb3Sn conductors when processed by rapid heating/quenching process. Therefore we have started an R&D program of Nb3Al conductors for future accelerator magnets. Several test wires of around 0.8 mm diameter, which have relatively small filament (similar to50 micron diameter) and low matrix ratio (similar to1.0), were fabricated, and the heat treatment and area reduction conditions after the rapid quenching process were studied. The highest noncopper J(c) achieved during this study was 1734 A/mm(2) at 10 T and 4.2
