Demands for the production of high purity ferromanganese alloys are increasing, because ferromanganese alloys are added to molten steels in the final stage of refining process. Although Mn-Si-C system is a fundamental system for the refining of ferromanganese alloys, reported thermodynamic information for the liquid solution is very scarce. Furthermore, solution properties of Mn-Si-C melts have not been clearly described because the liquid solution exhibits a high degree of short-range-ordering. In order to predict the thermodynamic properties of the liquid solution over the entire composition range, liquid phases of Si-C, Mn-Si, Mn-C and Mn-Si-C systems were optimized by the modified quasichemical model. Model parameters were optimized to best reproduce the phase diagrams and important thermodynamic properties in Mn-Si-C and its sub-binary systems. Using the model and optimized parameters, various thermodynamic calculations were carried out. The present database will be a part of larger thermodynamic database for the ferromanganese alloy database.
