不同固溶状态Mg-10Gd-3Y-1.2Zn-0.5Zr合金的力学性能及断裂行为周会会,宋鹏,黄太红,陆建生昆明理工大学摘 要:通过在Mg-10Gd-3Y-0.5Zr合金中添加少量Zn制备出一种新型Mg-10Gd-3Y-1.2Zn-0.5Zr合金,并利用扫描电子显微镜,拉伸试验机分析研究Mg合金不同状态下的显微组织,力学性能及断裂行为.结果表明:Mg-10Gd-3Y-1.2Zn-0.5Zr合金在不同的时效状态下,铸态塑性差,T4态塑性好,T6态塑性优于铸态但劣于T4态,且所有样品都是从脆性解理断裂为主,晶界和层状相界面比化合物界面结合牢固.通过比较3个不同温度下T6态的力学性能,发现提高固溶温度能提高合金的强度,但延伸率会略降.并且Zn促进层状相生长,但是对基体塑性提高作用有限.关键词......
