Abstract

Magnesium deoxidation equilibrium of molten Fe–Ni alloy was determined by a chemical equilibrium method at temperature of 1873 to 1973 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.
