The morphology and size distribution of MnS inclusions in AISI 1215 free cutting steel billet were studied.The results show that the sulfides evolve from type I to type II with the position moving from edge to center at the cross section.Based on Uhlmann model and chemical compositions of the billet,it is suggested that cooling rate and sulfur segregation play an important role in controlling the morphology and diameter of MnS inclusions.The increasing cooling rate facilitates the formation of type I MnS,but is unfavorable to the growth of MnS.Sulfur segregation contributes to the formation of type II MnS.
