半固态ZnAl27合金挤压成形金相组织研究

Study on the Microstructure of Extruded Semi-Solid ZnAl27 Alloys

对常规ZnAl2 7合金和经机械搅拌得到的半固态ZnAl2 7合金材料进行了挤压成形试验 ,分析了合金在挤压成形后得到的试件的金相组织。结果表明 ,半固态ZnAl2 7合金挤压成形件的组织极为均匀细小。

On the basis of the extrusion experiments on general ZnAl27 alloys and Semi-Solid ZnAl27 alloys obtained by mechanical mix, the microstructure of extruded pieces is analyzed. The results show that the microstructure of the extruded pieces is very homogeneous and fine.
