采用电弧熔炼法制备了新型钛基和锆基生物医用金属丝材。Zr基非晶合金丝材、Ti-Ti型Ti-Zr二元丝材和Ti-Ti型Ti-Nb-Ta-Zr（TNTZ）丝材具有较高的抗拉强度和良好的塑性。锆基金属玻璃丝具有极高的抗拉强度，超过1GPa，弹性应变极限达到2%左右。Ti-Zr二元合金在熔体抽拉过程中表现出很强的丝状成形倾向，得到了高Ti含量的Ti 90 Zr 10合金丝材。TNTZ丝显示出上级弯曲延展性，并且实现了完全延展性。
New Ti-based and Zr-based metallic wires for the future application as biomaterials were developed by arc-melting type melt-extraction method. Zr-based metallic glass wire, -Ti type Ti-Zr binary wire and -Ti type Ti-Nb-Ta-Zr (TNTZ) wire show high tensile strength and good vending ductility. Zr-based metallic glass wire shows extremely high tensile strength over 1GPa and large elastic strain limit reached approximately 2%. Ti-Zr binary alloy shows high wire-shape forming tendency during melt-extraction, and high Ti concentration Ti90Zr10 alloy wire was obtained. TNTZ wire shows superior bending ductility and full ductility is achieved.
