Abstract

Inclusion species formed in SS400 steel with Ce-addition was predicted by thermodynamic calculation. The analysis of the inclusion morphology and size distribution was carried out by applying Scanning Electron Microscopy (SEM) and Transmission Electron Microscope (TEM). Nano-Fe₃O₄ particles were also found in cerium-deoxidized and-desulfurized steel and their shapes were nearly spherical. The complex Ce₂O₃ inclusions covering a layer of 218 nm composed by several MnS particles with similar diffraction pattern. Most importantly, the complex Ce₂O₃ characterized by using TEM diffraction is amorphous in the steel, indicating that Ce₂O₃ formed in the liquid iron and then MnS segregated cling to it.
