Abstract

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