Abstract
In the conventional bronze technique of manufacturing multifilamentary Nb3Sn superconducting wires (Fig. 1), a composite billet having niobium cores in a bronze sleeve is hot-extruded and drawn down to a rod. The number of filaments is increased by assembling these rods into a starting billet, which is again hot-extruded and drawn. After the cycles of assembly and reduction are completed, the rod is drawn down to a fine multifilamentary wire. Intermediate anneals must be given frequently to soften the bronze matrix. Finally, a diffusion anneal produces Nb3Sn at the niobium-bronze interface.
