摘　　要：以KS282合金为研究对象,通过试验方法分析了脉冲电场对合金凝固过程及凝固组织的影响。试验表明,外加电脉冲能够有效的改善合金微观组织初生相形态,提高初生硅相形核率。Taking KS282 alloy as research object, the effects of pulsed electric field on solidification process and microstructure were analyzed through test method. Experiment results show that, an applied electric pulse can effectively improve the morphology of primary phase in microstructure, increase the nucleation rate of primary silicon.
