The inclusions composition, size, morphology and distribution in an Fe-30mass%Ni alloy were studied as a function of the initial solute contents, which were controlled by the CaO-Al<SUB>2</SUB>O<SUB>3</SUB> slags, and of the solidification parameters. The Al<SUB>2</SUB>O<SUB>3</SUB>-rich Al<SUB>2</SUB>O<SUB>3</SUB>-CaO inclusions were observed at the initial contents of Al=300-400 and O<6, while the FeO and the FeO-rich FeO-Al<SUB>2</SUB>O<SUB>3</SUB> inclusions were observed at the initial contents of Al=2-6 and O=20-130 on mass ppm base. The FeO-rich FeO-Al<SUB>2</SUB>O<SUB>3</SUB> inclusions were located in later stage of solidification in the intercellular or the interdendritic region. And most of the Al<SUB>2</SUB>O<SUB>3</SUB>-rich Al<SUB>2</SUB>O<SUB>3</SUB>-CaO inclusions were located in later stage of solidification, but some distributed in the intercellular or the interdendritic region. The dependence of the composition and the size of these inclusions on the cooling rate was not observed. The precipitation of FeO and Al<SUB>2</SUB>O<SUB>3</SUB> was discussed by using the solute segregation models.
