Abstract
Powder metallurgy processed submicron multifilamentary Nb3Sn superconducting wires were fabricated starting with 250–500‐μm‐diam powders. A multiple strand bundling procedure was used to simulate large scale production with actual areal reductions greater than 106 to achieve submicron fibers. Both external tin and tin core processing were successful. Typical Cu‐36 wt.% Nb‐Sn materials gave overall critical current densities of 8×104 A/cm2 at 12 T, 3×104 A/cm2 at 14 T, and 6×103 A/cm2 at 16 T. These results demonstrate that particle size and billet size can be scaled from earlier laboratory scale to large scale fabrication to produce high performance materials.Keywords
