摘要
按照临床上对外科植入材料的要求和现有医用钛合金存在的问题,制定了新合金设计的原则。确定了新合金添加合金化元素为Zr,Nb,Ta,合金的名义成分为Ti-12.5Zr-2.5Nb-2.5Ta,对新合金进行了组织结构分析与机械性能的测试。实验结果表明:该新型医用钛合金,满足了设计原则中对机械性能的要求。
According to clinical requirements for medical titanium alloys and flaws existing in present medical titanium alloys, a new titanium alloy has been designed and prepared. Zr, Nb, Ta were selected for composing elements of the titanium alloy. Titanium alloy' s nominal composition is Ti-12. 5Zr-2. 5Nb-2. 5Ta. Micrographs and mechanical properties of the new titanium alloy were analyzed and tested, the result shows that mechanical properties can meet design requirements.
