用定向凝固技术究研了单一稀土元素La对铸铁石墨形态的影响,发现随着加La量的增加,石墨形态从片状变到蠕虫状、球状;加入反球化剂Al,可使蠕虫状石墨范围扩大。
The directional solidification technique was used to study the effect of single rare earth element La on the morphology of cast iron graphite. It was found that the morphology of graphite changed from flake to worm-like and spherical with the increase of La content. Graphite expanded.
