摘要:
Nb3Al超导体的超导转变温度(Tc)和上临界磁场(Hc2)与Nb3Sn类似,但具有更好的应力应变容许特性和高场临界电流密度(Jc)。因此,被认为是下一代高场磁体应用的理想材料。目前国际上报道的Nb3Al超导线材单根长度可以达到2.6 km;在4.2K和15 T条件下,Jc达到1000 A/mm2;但是由于制备工艺的复杂性,目前仍然无法实现大规模工业化应用。本文结合Nb3Al超导材料的基本性质,系统介绍了Nb3Al超导线材前驱体的制备方法、热处理工艺和覆Cu工艺,对不同的制备方法进行了比较,重点分析了线材制备过程中存在的关键性难点问题;最后展望了Nb3Al超导材料的发展趋势。
Abstract:
The superconducting transition temperament (Tc) and upper critical magnetic field (Hc2)of Nb3Al superconductor are similar to Nb3Sn, but it has better strain tolerance and higher critical current(Jc)at high field. Therefore, Nb3Al superconductor is considered as a very appealing material for use in future high field application. At present, the Nb3Al superconducting wire with 2.6km-long length had been reported, which exhibited a large Jc of 1000A/mm2 at 4.2K and 15T. Due to the complexity of fabrication techniques, it can not be commercial application. In this paper, various precursor fabrication、heat-treatment and cladding Cu techniques are described and compared, and the difficulties of fabrication processes were analysed especially. In the end, a perspective and future development of Nb3Al superconductor was given.
