摘要：
An Nb 3 Sn wire rod having a high J c 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 Nb 3 Sn filament. Thus, an Nb 3 Sn extrafine multi-core superconducting wire is manufactured.
