Summary: | The combined deoxidation of Fe–Ni melts by manganese and aluminum at 1873 K is thermodynamically analyzed. The dependences of oxygen solubility on the manganese and aluminum content are calculated for the Fe–40% Ni melt. The combined deoxidation of the Fe–40% Ni melt by manganese and aluminum is experimentally studied in the range 0.1–0.3% Mn and 0.0005–0.056% Al at 1873 K. The oxygen concentration is found not to depend on the manganese content in the manganese content range under study (0.1–0.3%). The experimental data obtained are in good agreement with the results of thermodynamic analysis, from which it follows that the effect of manganese on the deoxidation ability of aluminum in the Fe–40% Ni melt in the range 0.1–1% Mn can be significant if the aluminum content is lower than 0.0005%. |
