摘要：

The formation of inclusion in Ti–Al complex deoxidized C–Mn steel was investigated. When Al content in steel is very low([Al]=0.0005%), for 0.003%<[Ti]<0.007%, the inclusion is the Al2O3–SiO2–MnO–TiOx composite inclusion; for [Ti]≥0.009%, the inclusion is TiOx in the steel. When [Ti]=0.005%, [Al]<0.001%, the inclusion is the Al2O3–SiO2–MnO–TiOx composite inclusion; while [Al]>0.006%, inclusions would be pure Al2O3. The experimental results agree with the thermodynamics conclusions.
