主　　题：9%Ni cast steel intergranular cracking rare earth 

摘      要：The intergranular cracking of 9% Ni cast steel seems mainly to relate to the segregation of contaminates H,S and P along *** addition of rare earth may eliminate the seg- regation of these contaminates along grain boundaries and improve the binding force among boundaries,so as to reduce remarkably the intergranular cracking.
