Abstract

Powder metallurgy processed multifilamentary Nb-8 wt.% Al wires were heat-treated at temperatures >2000°C for very short times. Values of Tc ranging from 12 to 20 K have been resistively measured from these wires after annealing them at 700 to 750°C for 48 to 185 h. The Bc2(T) values of the same samples were also measured, and the values of their magnetic slope (-dBc2/dT) at Tc varied in the range 2.38 to 2.58 T/K.
