Composite-processed multifilamentary Nb3Sn conductors are being developed for high-field applications, such as fusion reactor magnets. However, the improvement of critical current density, Jc, of the composite-processed Nb3Sn in high magnetic fields is required since the Jc decreases rapidly in fields above 12 T. Therefore, numerous studies have been made aiming at the improvement of Jc in high fields of the composite-processed Nb3Sn through alloying additions to the niobium core, or to the matrix, or to both.1–9
