Title: Manufacture of nb3sn superconductive wire material
Inventor: KAMATA KUNINAO
IPC: H01B12/10
Filed: 1990-06-08
Abstract: PURPOSE:To increase the critical current density and to reduce the AC loss by using an Nb-based alloy in which a minute amount of Ti, Hf, or Ta is added to the core. CONSTITUTION:In the manufacturing of Nb3Sn superconductor wire material, a compound material of an Nb-based alloy material including 0.5 to 5 atomic % of either one sort of Ti, Hf, or Ta, and a Cu-based alloy material including 3 to 8.5 atomic % of Sn is used as the said compound material, and processed. As a result, a ribbon-form deformation of a filament is suppressed, and the proximity effect is reduced. And since the adding of the alloy elements has a growth promoting effect of Nb3Sn, an Nb3Sn wire material of a low AC loss and a high critical current can be manufactured easily.
