Abstract

A.c. susceptibility measurements made on samples of Nb3Al have shown that, even after extensive heat-treatments, significant amounts of degraded A15 phases are present. This low critical field material, resulting from vacancies on the niobium chains, limits the current carrying capacity of the bulk sample. The indication is that under favourable conditions the critical current density of Nb3Al could equal or be superior to that of Nb3Sn.
