采用电弧熔炼法制备了具有上级弯曲塑性和超过2GPa的超高抗拉强度的Ni-Nb基二元和三元非晶丝材。从Ni 60 Nb 20 M20（M=Ti、Zr、Hf、V、Nb和Ta）合金获得没有厚氧化物层和表面粗糙度的连续金属玻璃丝。然而，在Ni 60 Nb 20 M20（M=Cr、Fe、Co、Cu、Al、Si和Sn）合金中没有获得非晶相;此外，仅由Ni-Nb-Fe合金形成连续的金属结晶线。在Ni-Nb基合金中，非晶相的形成有利于电弧熔炼型熔拔法形成连续金属丝。
Ni–Nb-based binary and ternary metallic glass wires with superior bending ductility and extremely high tensile strength exceeding 2GPa were prepared by the arc-melt-type melt-extraction method. Continuous metallic glass wires without a thick oxide layer and surface roughness were obtained from Ni60Nb20M20(M=Ti, Zr, Hf, V, Nb, and Ta) alloys. However, an amorphous phase was not obtained in Ni60Nb20M20(M=Cr, Fe, Co, Cu, Al, Si, and Sn) alloys; further, a continuous metallic crystalline wire was formed only from the Ni–Nb–Fe alloy. In Ni–Nb based alloys, amorphous phase formation is favorable for the formation of continuous metallic wires by the arc-melt-type melt-extraction method.
