Critical review of thermodynamics of deoxidation of molten iron by Cr, V, Al, Zr, and Ti has been made. Experimental [wt.% O] vs. [wt. % M] data in these systems have been used to estimate first and second order cross-interaction parameters (eMO, rMO) employing five different calculation models. It was found that rMO should be considered for best fit. On the basis of this exercise, a simple analytical equation relating [wt.% O] and [wt.% M] has been proposed and values of eMO, rMO recommended. Assessments have also been made of deoxidation constants (K). Values of K for the above systems have been proposed based on selected experimental data and thermodynamic estimates. [wt.% O] vs. [wt.% M] solubility curves for molten iron in equilibrium with oxide product calculated from the accepted values of thermodynamic parameters, have been presented.
