Abstract

The effect of greatly restricting heat treatment time and temperature, as well as the strain space between heat treatments was investigated for a high homogeneity Nb46.5wt% composite. The number of heat treatments was 3 or 6. It was found that the crucial heat treatment was the final one and that the initial ones could be considerably restricted. A strong linear relationship was found between J c (5T, 8T) and the % α-Ti for J c (5T) values ranging from ~ 950–3050 A/mm2 and α-Ti contents ranging from 2.5 to 21 vol%.
