采用电弧熔炼法制备了生物医用锆基非晶合金丝材，并对其性能进行了测试。在常规Zr-Al-Ni-Cu、无Ni的Zr-Al-Co-Cu、无Ni和Al的Zr-Ti-Co合金中获得了具有良好白色光泽和表面光滑的连续金属玻璃丝。Zr基金属玻璃丝具有高的抗拉强度，达到1 GPa。此外，金属玻璃丝显示出良好的弯曲延展性，并且可以弯曲180度而不断裂。Zr基金属玻璃丝同时实现了高的抗拉强度、良好的弯曲延展性和高热稳定性。[doi：10.2320/matertrans.MRA2008006]
New Zr-based metallic glass wires with and without bio-toxic elements of Ni and Al for the application to biomaterials were prepared by arc-melting type melt-extraction method and their characteristics were tested. The continuous metallic glass wires with a good white luster and smooth surface were obtained in various alloys such as conventional Zr-Al-Ni-Cu, Ni-free Zr-Al-Co-Cu, and Ni and Al free Zr-Ti-Co alloys. The Zr-based metallic glass wires exhibit high tensile strength reaching 1 GPa. Furthermore, the metallic glass wires showed good bending ductility and could be bent through 180 degrees without fracture. The Zr-based metallic glass wires achieve simultaneously high tensile strength, good bending ductility and high thermal stability. [doi:10.2320/matertrans.MRA2008006]
