摘要:

Powder metallurgy is used as an alternative process to produce Nb3Sn and V3Ga composite superconductors with large critical transport currents in magnetic fields above 15T. Whereas for a Cu–30 wt.%Nb +Sn composite the overall current densityJcamounts to 1.0×108A/m2at 16T, values in excess of 4×108A/m2(16 T) are observed for Cu–30 wt.% V+Ga composites.
