背景技术
近年来,各个技术发达国家都将第二代涂层超导体的实用化研究作为21世纪超导材料研究和发展的热点,并取得了一系列突破性的进展。目前,在采用RABiTS技术路线来发展涂层超导带材的过程中,多种金属带材可用来作为涂层超导材料的韧性织构基带材料,其中,镍钨合金基带是研究最广泛的合金体系,但是高性能的镍钨合金的加工成本较高,限制了镍钨合金基带的进一步发展。研究表明,铜镍合金容易形成强立方织构,通过铜和镍的比例调整可以在液氮温区实现无铁磁性,但其力学性能较差,由于铜镍合金在原材料的成本上具有明显的优势,关于铜镍合金的研究仍然具有重要的工业价值,如何在铜基合金中获得高的力学性能是目前第二代涂层超导带材基带领域研发的热点也是难点。
