Abstract

Nb₃Al prepared in the ductile bcc phase by quenching, followed by mechanical working, followed by conversion to the A-15 structure is found to carry currents above 10⁹ A/m² in fields near 20 T. These critical currents are comparable to those found in Nb₃Ge and V ₃Ga, the closest competing materials for use in high fields. Further enhancement of J_c is possible if thermal treatments are optimized.
