“…The chemical equilibrium was achieved by equilibrating a prepared Fe-Al-Co alloy with Ag at 1 823 K which was similar to previous report. 14) To prepare the Fe-Al-Co alloy, electrolytic iron, reagent grade of metallic Al and Co were melted and quenched using an arc furnace. In order to suppress Al oxidation during melting, reagent grade of metallic Ti was placed in the chamber of the arc furnace and melted in prior to the target alloy to remove oxygen inside the chamber.…”

Nowadays Al is commonly used as deoxidizer and sometimes alloying element. On the other hand, due to the increase in scrap addition, suppress in the concentration of tramp element in molten steel during refining process becomes more important than ever. Co is one of the tramp elements in steel scrap and its content is increasing due to the increase in the production of Co materials world widely. As fundamentals to understand the thermodynamic behaviors of Co in the molten steel containing high Al, the interaction parameter between Co and Al has been measured in this study through a chemical equilibrium method. From the equilibrium composition of the Fe-CoAl alloy and Ag, the interaction parameter between Co and Al in molten Fe-CoAl alloy was determined as follows, ε Co Al = 7.3 ± 0.9 at 1 823 K, 0 < X Al Fe < 0.14 By converting the temperature and the reference state, the following values were also obtained, ε Co Al = 6.

“…Recently, the interaction coefficients of alloying elements with tramp elements in molten Fe were reported. [38][39][40][41][42] However, data on the interaction coefficients of transition elements with tramp elements in molten alloy steels have been very limited. In our previous work, the interaction coefficients of boron (B), cobalt (Co), and Ni with Cu 41) and those of Mo, B, Ni, titanium (Ti), and niobium (Nb) with Sn in molten Fe 42) were reported.…”
