本文评价了多芯Nb_3Sn和V_3Ga的各种加工工艺;对比了用青铜法和外部扩散法制造的商用Nb_3S_n的临界电流,其中也包括原位法和粉末法的临界电流;讨论了有希望改善J_c的新发展。
In this paper, various processing technologies of multi-core Nb_3Sn and V_3Ga were evaluated. The critical current of commercial Nb_3S_n fabricated by bronze method and external diffusion method was also compared. The critical current of in-situ method and powder method were also discussed. New development.
