摘　　要：对Pb-Ca-Sn-Al四元合金的金相组织结构进行研究,采用了定浓度电解液恒流电解腐蚀技术和偏光金相显微镜,研究发现合金的工作方式和成分直接影响合金的组织特征。通过在某特定电解液浓度下,用恒电流对合金样品进行电解腐蚀实验,并检验腐蚀后的样品金相,发现该合金的腐蚀主要是沿晶界腐蚀,并且腐蚀过程会伴随晶粒析出。The microstructure of four element alloy Pb-Ca-Sn-Al was studied.By using constant current electrolytic corrosion technology of constant concentration electrolyte and polarizing optical microscopy,it's found that the working and composition of alloy system directly affect the microstructure of alloy.Through the electrolytic corrosion experiment with constant current of alloy samples at a particular concentration of electrolyte and testing the etched metallographic specimen,it's found that the corrosion of the alloy is mainly intergranular corrosion,and the separate grains are generated in corrosion process.
