Nb_3Al超导体具有极高的临界电流密度（J（c））和优异的应变耐受性，被认为是高场磁体应用中Nb_3Sn的替代品。然而，Nb_3Al相形成的复杂性阻碍了Nb_3Al超导线材目前满足工程应用的要求。在这里，我们已经报道了改进的性能的简单结构的18-双辊双辊Nb 3Al前体长线材制造的快速加热和淬火（RHQ）过程。在各种加热条件下用RHQ热处理处理后，在700摄氏度至1100摄氏度之间的温度下对Nb 3Al线材进行后热处理。研究了超导线材的相形成和超导性能。已经发现，即使RHQ工艺偏离最佳工艺状态，也可以通过适当地选择后热处理条件来改善线材的超导性能。
With extremely high critical current density (J(c)) and excellent strain tolerance,Nb3Al superconductor is considered as an alternative to Nb3Sn for application of high-filed magnets. However, complexity in the phase formation of Nb3Al hinders the Nb3Al superconducting wires to satisfy the requirement of engineering applications at present. Here, we have reported the improved performance of simple-structured 18-filamnet jelly-roll Nb3Al precursor long wires fabricated with rapid heating and quenching (RHQ) process. After processed with RHQ heat-treatment under various heating conditions, the Nb3Al wire were post-heat treated at a temperature between 700 degrees C to 1100 degrees C. The phase formation and the superconducting properties of the wires were investigated. It has been found that, even if the RHQ process deviates from the optimum processing state, the superconducting properties of the wire can be improved by appropriately selecting post-heat treatment conditions.
