摘　　要：采用扫描电子显微镜和能谱微区分析，研究了以全新炉料和新旧炉料两种不同炉料搭配方式生产铸造锌铝合金铸件，并对其在铸态和经均匀化处理后的显微组织和成分进行比较，发现采用全新炉料搭配比采用新旧炉料按1：1搭配的铸造锌铝合金显微组织均匀、力学性能好；在相同条件下，经均匀化处理比铸造状态下的综合性能好。This paper studies producing zinc- aluminum cast alloy casting by using two kinds of composition such as new burden and t mixed burden. The microstructure and composition in cast and homogenizing treatment have been compared and studied by ,wanning electron microscope and energy spectrum analysis. The result shows that the microstructure and mechanical properties of zinc- aluminum cast alloy produced by using new burden is better than the using the new and used burden mixed in the ratio of 1 ： 1, and under same conditions, the homogenized alloy＇s comprehensive properties is better than the cast alloy.
