| description | During decades before the evolution of more powerful computational tools,
simplified formalisms such as the Wagner dilute solution formalism, have been
successfully used in the study of deoxidation reactions of steel. This
formalism relies on the introduction of interaction coefficients to account
from deviations from Henry’s Law. With the evolution of thermodynamic
modeling and of the CALPHAD method, the fact that thermodynamic descriptions
using these parameters were derived to be used at relatively dilute solution
has been sometimes overlooked and the formalism has been criticized for
deviating from reality in non-dilute solutions. In this work, it is shown
that the interaction parameters used in this formalism correlate with
properties of the solutes and of the solvent. The work focuses on the
interactions in systems Fe-M-O, where M is a deoxidant. Correlations between
interaction coefficients and heats of formation of the corresponding oxides
and with the atomic number of the deoxidants are demonstrated. This not only
helps supporting the physicochemical soundness of the formalism but also
provides a way of checking the consistency of data presented in this formalism. |
