Nb3Al超导体具有极高的临界电流密度（J(c)）和优异的应变容限，被认为是Nb3Sn超导体在高场磁体应用中的替代品。然而，由于Nb3Al超导导线结构复杂，目前还难以满足工程应用的要求。在这项工作中，我们报道了一种单芯结构果冻卷状Nb3Al前驱体长丝的制造。利用自制的快速加热淬火（RHQ）设备，成功地对Nb3Al线样品进行了不同加热条件下的RHQ热处理，重点研究了快速加热淬火相变（RHQT）法焦耳加热电流对线材相形成和超导性能的影响。(C) 2018 Elsevier B.V.版权所有
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-field magnets. However, owing to their complex structure, Nb3Al superconducting wires can hardly meet the requirement of engineering application at present. In this work, we have reported the manufacture of a single core-structured jelly-roll Nb3Al precursor long wire. While using homemade rapid heating and quenching (RHQ) equipment, we have successfully carried out RHQ heat-treatment of Nb3Al wire samples with various heating conditions, especially the effect of the Joule heating currents by rapid heating, quenching and transformation (RHQT) method on the phase formation and the superconducting properties of the wires were investigated.
