中文摘要: 采用传统的铸锭冶金法制备实验合金,利用拉伸试验、金相组织观察、SEM扫描以及TEM透射等实验方法,研究了稀土元素Er对5083合金微观组织及力学性能的影响.结果表明,稀土元素Er的加入,在结晶过程中形成了一种粗大化合物,这种粗大化合物对合金的力学性能不利.
Abstract:The experiment alloys were prepared by the conventional ingot metallurgy method.By means of tensile properties measurement,observation of metallographic,SEM and TEM,the effects of Er on the microstructure and properties of 5083 alloy were investigated.The results show that some massive compounds were formed by the addition of Er in the course of crystallization.The massive compounds were adverse to the properties of 5083 alloy.
