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 Jc is possible if thermal treatments are optimized.
