Magnesium deoxidation equilibrium of molten Fe-Ni alloy was determined by a chemical equilibrium method at temperature of 1 873 to 1 973 K. Extreme care was taken for oxygen analysis of the samples. Numerical analysis on Mg deoxidation of molten Fe-Ni alloy has been carried out by utilizing the model based on Darken's quadratic formalism and Redlich-Kister type polynomial.
