| Abstract: | Experiment result that the rare earth elements added into 430 stainless steel has apparently improved its solidification structure has been reported in this paper,such as fractionize columnar grains,and enlarge the area of central fine equiaxed grains.And the mechanism of the effect of rare earth elements on structures of high alloys has been analyzed. |
