The solution model of Mn–Fe–Si–C system is essential in the development of high Mn containing steels and alloys, and its effectiveness depends on the well established information of constituting lower order systems. The solution property of Mn–Si system, which is one of such constituting binary systems, is not well established yet because the experimental data are limited in number and scope. The present study determines the temperature independent partial enthalpy and excess entropy of Mn and Si from the relevant experimental data. The resulting excess Gibbs free energy function was found to adequately describe the solution properties of Mn–Si system.
