Equilibrium between Titanium and Oxygen in Liquid Fe-Ti Alloy Coexisted with Titanium Oxides at 1873 K

Abstract

The equilibrium between Ti and O has been investigated in molten Fe–Ti alloy saturated with various kinds of titanium oxides at 1873 K. The present results have been thermodynamically analyzed applying Wagner's formalism as well as Darken's quadratic formalism with the excess Gibbs free energy change of mixing described by Redlich–Kister type polynomial. The equilibrium constants and the interaction parameters of Wagner's formalism were given as follows at 1873 K in the present work.
