A Zn-3Mg-1Ti alloy was fabricated by ultrasonic treatment of Zn-Mg alloy melt using a Ti ultrasonic radiation rod. The microstructure, phase structure, mechanical properties, degradation property, and in vitro cytotoxicity were investigated systematically. The obtained Zn-3Mg-1Ti alloy is composed of the Zn, MgZn, and TiZn. Owing to the grain refinement and second phase reinforcement, the mechanical properties of Zn-3Mg-1Ti alloy is improved. In addition, the Zn-3Mg-1Ti alloy exhibits minimal cytotoxicity compared to pure Zn and Zn-1Ti alloy. Electrochemical tests show that the Zn-3Mg-1Ti alloy has an appropriate degradation rate in Hank's solution.

采用钛超声辐射棒对锌镁合金熔体进行超声处理制备了一种Zn-3Mg-1Ti合金。系统研究了其微观结构、相结构、力学性能、降解性能和体外细胞毒性。所制备的Zn-3Mg-1Ti合金由Zn、MgZn和TiZn组成。由于晶粒细化和第二相强化，Zn-3Mg-1Ti合金的力学性能得到改善。此外，与纯锌和Zn-1Ti合金相比，Zn-3Mg-1Ti合金表现出最小的细胞毒性。电化学测试表明，Zn-3Mg-1Ti合金在汉克氏溶液中具有合适的降解速率。
