采用铜模吸铸法制备(Zr0.55Al0.1Ni0.05Cu0.3)100-xTix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144h后,(Zr0.55Al0.1Ni0.05Cu0.3)100-xTix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.
