摘要
在铜银合金晶粒组织的检测方法中,浸蚀剂的选取和晶粒的分析是关键。试验结果表明,由2g硝酸铁和50mL无水乙醇的混合液组成的浸蚀剂,适用于Cu-0.1%Ag合金晶粒的显示,金相组织的晶界清晰和晶粒完整。经过显微镜观察,合金的显微组织主要由单相Cu固溶体组成,并出现了等轴晶、孪晶、柱状晶和纤维组织,这与合金的性能密切相关。
The selection of etchant and the analysis of grain are the key to test method of grain of Cu Ag alloy.The results show that etchant composed of a mixture of 2g ferric nitrate and 50mL anhydrous ethanol is suitable for displaying the grains of Cu-0.1%Ag alloy.The grain boundary of metallographic structure is clear and the grains are complete.The microstructure of the alloy is mainly composed of single-phase Cu solid solution,and equiaxed grains,crystal twin,columnar grains and fibrous tissue appear,which is closely related to the properties of the alloy.
