The effect of Mn additions on the hysteresis loss and critical current density of power-metallurgy processed superconducting Nb/sub 3/Sn wires

Abstract

Powder-metallurgy processed Nb/sub 3/Sn conductors were fabricated using a (Cu-1 or 3 wt.% Mn)-22.5 wt.%Nb composite. Plasma rotating electrode processed powders were used to improve workability. The Mn addition to the matrix increased the critical current density. The overall critical current density was about 1.5 approximately 2 times higher than that of… (More)
