| 摘 要： | 采用激光共聚焦显微镜和透射电镜探究了稀土元素Ce对含Cu取向硅钢铸态组织和析出物的影响。结果表明,稀土元素Ce对含Cu取向硅钢铸态的组织能起到细化晶粒的作用;未加Ce的铸锭中存在粗大的(Cu,Mn)S+AlN粗大复合析出物,以及少量MnS和Cu2S单独析出物;稀土Ce的加入不改变析出物的类型,但使析出物数量明显减少、尺寸有所增大。

| Abstract: | Effect of rare earth element Ce on the as-cast microstructure and precipitates of Cu-containing grain-oriented silicon steel was investigated by means of laser scanning confocal microscope and transmission electron microscope. The results show that rare earth element Ce can refine grains in the as-cast microstructure of the Cu-containing grain-oriented silicon steel. In addition, there are coarse (Cu,Mn)S+AlN composite precipitates and a small amount of separate precipitates including MnS and Cu2S in the ingot cast without Ce addition. By adding Ce, the types of the as-cast precipitates do not change, while their amounts decrease significantly and their sizes increase somewhat. |
