摘　　要：The（Zr_（0.55）Al_（0.1）Ni_（0.05）Cu_（0.3））_（100-x）Ti_x alloys were prepared using an in-situ suck-casting method in a copper mold. The effects of Ti addition on the microstructure, mechanical and corrosion properties of the（Zr_（0.55）Al_（0.1）Ni_（0.05）Cu_（0.3））_（100-x）Ti_x alloys were investigated by X-ray diffraction, scanning electron microscopy, compressive tests and corrosion tests. It has been found that the addition of Ti higher than 4%（mole fraction） causes the formation of many crystalline phases in the alloy. The alloys with 1%-3% Ti display an obvious yield stage on their compressive stress-strain curves. An appropriate addition of Ti can improve the strength and ductility of the alloys. All the alloys have high corrosion resistance in 1 mol/L Na OH solution, and are corroded in 1 mol/L HCl solution. However, the appropriate addition of Ti can significantly improve the corrosion resistance of the alloys in HCl solution.采用铜模吸铸法制备（Zr_（0.55）Al_（0.1）Ni_（0.05）Cu_（0.3））_（100-x）Ti_x合金,利用X射线衍射、扫描电镜、压缩实验及腐蚀测试等手段研究Ti对合金显微组织、力学和腐蚀性能的影响。结果表明,当Ti含量高于4%（摩尔分数）时,合金中出现大量晶化相;而当Ti含量为1%~3%Ti时,合金的压缩应力-应变曲线上出现屈服现象。添加适量的Ti元素能提高合金的强度及韧性。在1 mol/L NaOH溶液中浸泡144 h后,（Zr_（0.55）Al_（0.1）Ni_（0.05）Cu_（0.3））_（100-x）Ti_x合金质量无明显变化,表现出良好的耐腐蚀性能;而在1 mol/L HCl溶液中则会发生腐蚀,但适量的Ti元素添加可显著提高合金在盐酸溶液中的耐腐蚀性能。
