The effect of Ta additions on the critical currents, J /SUB c/ , and upper critical fields, H /SUB c2/ , been examined. The Ta segregates to the Nb dendrites and causes no observable change in filament morphology. Both high field values increase to a maximum at 10 wt pct Ta in the Nb-Ta phase and drop for higher Ta contents. Improvement in J /SUB c/ in the 12 to 16 T range is small. The J /SUB c/ values of in situ wires are equivalent to bronze processed wires up to 12T but above that value they become lower.
