Abstract

The interaction parameter between Mo and Al in molten Fe-Al-Mo alloy was measured using a chemical equilibrium technique. A molten Fe-Al-Mo alloy was equilibrated with molten Ag in an Al2O3 crucible at 1823 K. The activity coefficient of Mo in Fe-Al alloys was measured as

εMoAl = –6.4 ± 0.8 at 1823 K (0 < XMo < 0.03)

Using the above interaction parameter, the influence of Mo on the deoxidation equilibrium of Al and O was estimated. The results indicate that the existence of Mo affected little on the equilibrium concentration of O in an Al-containing steel.
