Thermodynamic Self-interaction of Si in Ferritic Fe-Si Alloys

In order to clarify the thermodynamic properties of Si in ferritic Fe-Si alloy, equilibrium experiments were carried out with Fe-Si foils and Ag-Si alloys. The activity coefficient of Si at infinite dilute solution and the self-interaction parameters of Si were investigated from the distribution equilibrium of Si between the Fe and the Ag alloys. The self-interaction parameters of Si in the ferritic Fe-Si alloy were determined from 1323 K to 1423 K as follows:
$$ \varepsilon_{\text{Si}}^{\text{Si}} = - \frac{44065.8}{T} + 3.17 $$
