The results show that,besides forming inclusions, most of Ce atoms concentrate in graphite firstly. As theCe content increase, the concentration of Ce in graphite tends to saturate, relati-vely large amount of Ce dissolves in the alloy. Usually, the sulphur also concen-trates in graphite, however, it may exist in the form of FeS at the eutectic colonyboundaries, if the concentration of S is at a quite high level. Very little amountof S dissolves in the alloy. The morphology of graphite depends upon the degreeof saturation of Ce. It appears as nodula when Ce was saturated, and as vermicularwhile it was semi-saturated.
