摘要
Ni9铸钢晶界裂纹的形成主要与晶界偏聚杂质元素H,S,P有关;添加稀土后,消除了杂质元素H,S,P在晶界的偏聚,加强了晶界结合力,使晶界裂纹倾向明显降低。
The grain boundary cracking of the cast steel Ni9 seems to be mainly related tothe segregation of contaminantes H, S and P along boundaries. An addition of rare earth mayeliminate the segregation of these contaminantes along grain boundaries and improve the bind-ing force among boundaries, so as to reduce remarkably the grain boundary cracking.
