Abstract

Although thermodynamic interaction between titanium and silicon in molten iron is greatly important to precisely control Si-Ti complex deoxidation of liquid steel and titanium inclusions formation in the steelmaking process, the reported values of the interaction parameter between titanium and silicon in molten iron show large discrepancies. In the present work, the equilibration of molten Fe-Ti-Si alloy with both Ti3O5 and Ti2O3, which provides the controlled activity of titanium, was performed at 1873 K and the interaction parameter was determined.
