The Mn–Ni–Si system has been investigated via thermodynamic modeling coupled with key experiments. The isothermal section at 1000 °C of the Mn–Ni–Si system was determined by means of XRD and SEM/EDX. Based on the critically reviewed experimental data available in the literature and the present experimental data, a thermodynamic modeling of the Mn–Ni–Si system was performed. One single function was used to describe the Gibbs energies of both the ordered and disordered phases including L12 and Fcc_A1 as well as Bcc_B2 and Bcc_A2. Comprehensive comparisons between the calculated and measured phase diagrams showed that the measured isothermal sections at 800 and 1000 °C are satisfactorily accounted for by the thermodynamic description. A set of self-consistent thermodynamic parameters of the Mn–Ni–Si system has been obtained. The complete liquidus projection and reaction scheme of the Mn–Ni–Si system were also presented.
