The microscopic analysis results indicate that deposited metal is hypereutectic structure. 测试结果表明熔敷金属为过共晶组织。
The results show that the as-deposited microstructure possesses the feature of whole equiaxed grains and fine distributed micro cavities on the grain boundaries. 沉积态高镁铝合金基体呈全部等轴晶组织并存在少量显微孔洞是沉积态组织的主要特征。
