摘　　要：研究了保温电磁搅拌和间断性电磁搅拌对ZA2 7合金组织的影响。在保温凝固过程中进行电磁搅拌时 ,晶粒细化效果更明显。保温搅拌温度存在搅拌效果最理想的临界值TC。间断性电磁搅拌使得枝晶显著粒化 ,晶粒分布更加均匀。Effects of electromagnetic continuous and discontinuous stirring at holding temperature on the microstructure for ZA27 alloy were investigated. Grain size can be refined effectively and a ideal critical value T C on stirring effect exists with electromagnetic continuous stirring at holding temperature while grain size was sphered remarkablly and distributed uniformly with discontinuous electromagnetic stirring.
