A thermodynamic description of the Mg-Si binary system was obtained. The term “thermodynamic description” means that a set of thermodynamic model parameters was obtained, on the basis of which the Mg-Si phase diagram as well as any of the single-phase thermodynamic properties can be calculated. The model parameters were obtained by optimization with experimental phase equilibrium and thermodynamic data available in the literature. The present description has fewer model parameters than the previous ones published in the literature, while the agreement of the model-calculated thermodynamic properties and phase boundaries with the experimental data is as good or better than those of early descriptions. The computer program used to optimize the model parameters was WinPhaD, developed by CompuTherm LLC.
