| 摘 要： | 文章研究了电磁搅拌对纯Al铸件凝固结晶的影响。研究结果表明 :电磁搅拌对纯Al组织改善很大 ,使粗大的柱状晶变成细小的等轴晶 ;而且 ,随着搅拌电压的增大 ,柱状晶区越小 ,等轴晶区越大 ,晶粒越细小 ;交旋搅拌比单旋搅拌效果更好。

| Abstract: | The article has probed into the effect of electromagnetic agitation on pure Al solidifying crystals of casting. The result is that electromagnetic agitation can improve the structure of pure Al by changing big columnar crystals into small isometric ones; and with the increase of agitation voltage, the columnar crystal area will become larger and the isometric crystal area will become smaller, thus smaller crystal grains; alternate-turn agitation is more effective than single-turn agitation. |
