Abstract
Aluminum deoxidation equilibrium of molten Fe-Ni alloy was determined by chemical equilibrium method at temperature of 1873 to 1973 K. Also, critical point in molten Fe-40mass%Ni alloy that coexisted with AI 2O 3 and FeO. AI 2O 3 was determined experimentally at 1973 K. Solvent extraction method was applied to improve the analytical accuracy of the low aluminum content in molten Fe-Ni alloy. The relation between aluminum and oxygen contents in molten Fe-Ni alloy equilibrated with AI 2O 3 or FeO. AI 2O 3 was estimated in the whole alloy composition range at 1873 to 1973 K by utilizing the metallic solution model based on Darken's quadratic formalism and Redlich-Kister type polynomial.
