Processing Limits for Ultrafine-Multifilament Nb3SN

Abstract

The bronze process has been successful in producing composite wires with 1-μm-diameter Nb3Sn filament [1,2]. Early success in fabricating complicated ultrafine-filament wires, which included tantalum-fin eddy-current barriers, has not been easily extended to a reproducible manufacturing process. Although multifilament Nb3Sn conductors are still not as readily or reliably available as those of NbTi, they remain very attractive for applications where high current density and operating temperature are important [3]. The fundamental processing limits for ultrafine Nb3Sn discussed herein are the result of an extensive assessment of Nb3Sn production problems.
