Abstract:
An Nb3Sn wire rod having a high Jc value is manufactured using an Ag—Sn alloy. A composite rod including a plurality of Nb core materials incorporated in an Ag—Sn alloy matrix material having an Sn concentration of 9.35 to 22.85 at % is prepared. Next, the composite rod is extruded and/or wire drawn while carrying out process annealing of 350 to 490° C., followed by heat treatment at 500 to 900° C. to produce an Nb3Sn filament. Thus, an Nb3Sn extrafine multi-core superconducting wire is manufactured.
