采用管内粉末（PIT）技术制备了铌铝带的前驱体。采用高能球磨法制备Nb-Al粉末过饱和固溶体，然后采用管内粉末法制备Nb3Al系列前驱体带。与常压烧结相比，热压烧结大大提高了带的临界电流密度。结果表明：采用管内粉末法和热压烧结法制备的Nb3Al带，其jc （8 K, 0 T）值均高于6 × 105A/cm2；在20 MPa压力下压制，在950°C下烧结3 h后的Nb3Al带具有最佳的磁通钉扎性能，样品在2.2 T磁场下的最大磁通钉扎力（Fp,max）达到3.28109 N/m3。
The precursors of Nb-Al tape were fabricated by a powder-in-tube (PIT) technique. Supersaturated solid solutions of Nb-Al powder were obtained by high-energy ball milling, followed by a powder-in-tube process to prepare series of Nb3Al precursor tapes. Compared with sintering under normal pressure, the hot-pressing sintering greatly increased the critical current density of the tapes. The results showed that the Nb3Al tapes prepared via the powder-in-tube method and hot-pressed sintering could significantly improve theJcperformance, and the value ofJc(8 K, 0 T) was higher than 6 × 105A/cm2. The Nb3Al tapes after pressing under the pressure of 20 MPa and sintering at 950∘C for 3 h had the best magnetic flux pinning performance, and the sample reached the maximum flux pinning force (Fp,max) of 3.28109 N/m3in the magnetic field of 2.2 T.
