Abstract��Self��lubrication alloys containing sulphide with different contents of manganese were prepared by a induction melting and casting process. The formation of sulfide in these alloys and their fracture were researched both with a scanning electron microscope and microstructure analysis. The results show that the fracture surface is in form of brittle cleavage fracture when sulfides locate in pearlite with a low toughness, and the fracture surface is in form of ductile dimple fracture when sulfides locate in ferrite with a high toughness. The sulfides mainly include FeS and present as a composite phase containing some small hard particles of V, Nb, Ti sulfides for the alloy with a lower content of manganese, whereas the sulfides mainly comprise MnS for the alloy with a high content of manganese.
