The effect on improving the properties of Ni-base alloy was studied in this paper based on variation in adding amount of rare-earth metals. The results showed that, through introducing suitable amount of rare-earth metals in Ni-base corrosion-resistant alloy, the alloy grain can be refined remarkably, the morphology and distribution of carbides can be improved, agglomeration of carbides can be prevented, the amount of non-metallic inclusions can be reduced, the inclusions can be minimized, spheroidized and ...
