... performance. Critical Current Density Though the mechanism of flux pinning in the A15 compounds is not well understood ( Ref 20 ), it is clear that grain boundaries are the important pinning centers ( Fig. 13 ) ( Ref 14 ). The critical current density generally scales well and the flux-pinning force...

...% Ti) due to enhanced flux pinning characteristics ( Ref 6 ). The trade-off, however, for higher current-carrying capacity and lower alloy cost (by replacing niobium with titanium) is decreased ductility. Theory predicts an upper critical field ( H c2 ) of 17 to 18 T for binary NbTi. As indicated...
