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 V3Ga, the closest competing materials for use in high fields. Further enhancement of Jc is possible if thermal treatments are optimized.Keywords
