Through the study of metallographic specimen and the inclusions through electrolyzation under SEM, it is indicated that the Ti-deoxidized products are globular compound inclusions with the size of 1~3μm in this experiment condition. With the technical of ion beam thinner the inner structure of these inclusions can be observed, whose core is Ti-O and outer is Mn-S. Based on EBSD the phase composition has been analyzed and it indicated that these globular compound inclusions are Ti2O3 and MnS with nucleating center Ti2O3, which can prompt to nucleate IGF.
