文章编号: 1004-0609(2004)10-1729-07 加钛方式与钛含量对A356合金组织和性能的影响 宋谋胜, 刘忠侠, 李继文, 宋天福, 王明星, 谢敬佩, 翁永刚 (郑州大学 物理工程学院, 材料物理教育部重点实验室, 郑州 450052 ) 摘 要: 研究了不同钛含量的电解A356合金的组织和力学性能, 并与相应钛含量的熔配加钛A356合金进行了比较. 结果表明: 随着钛含量的增加, 二者的晶粒和一次枝晶都明显细化, 硅颗粒尺寸, 纵横比均有所降低, 硅颗粒圆形度有所增加, 意味着硅颗粒形状得到改善. 但当钛含量大于0.1%时, 这种影响变弱. 钛含量和加钛方式对合金的屈服强度和抗拉强度影响不大且二者相当, 但塑性随着钛含量的增加而增加, 当钛含量达到0.1%时, 两种合金均具有最佳的塑性和质量系数. 对具有相同钛含量的合金, 电解加钛A356合金的晶粒......
