研究了轴向和横向应力对铌管加工多丝Nb3Al线临界电流的影响。这些 Nb3Al 线由于轴向或横向应力而导致的临界电流的衰减比 Nb3Sn 线的小得多。通过微观观察和弹性理论研究了 Nb3Al 线的微观结构和应力状态，以了解临界电流的应力依赖性。从工程角度来看，嵌入超导丝的基体材料的机械强度非常重要，特别是对于横向应力效应。
Effects of axial and transverse stress on the critical current of Nb-tube processed multifilamentary Nb3Al wires have been studied. The degradations of the critical current due to axial or transverse stress for these Nb3Al wires are much smaller than those for Nb3Sn wires. The microstructures and stress states of the Nb3Al wires have been investigated to understand the stress dependences of the critical current through the microscopic observations and the elastic theory. From an engineering standpoint, the importance of mechanical strength of the matrix material where superconducting filaments are embedded has been found especially for transverse stress effects.
