| Abstract: | In this paper,the effects of rare earth metal additions on the as-cast microstructure and formation of intermetallic compounds in the commercial-purity aluminum have been investigated by means of optical microscopy,SEM and X-ray diffractometry.The results show that both the as-cast grain size and the secondary dendrite arm spacing are decreased by adding cerium and lanthanum metals.Cerium and Lanthanum mainly form the binary or ternary intermetallic compounds with Si and Fe |
