ժҪ The thermodynamic database of the Fe��C��Mn��Si system has been developed in the framework of the CALPHAD approach. The sub��ternary systems have been carefully evaluated and revised based on available experimental data. A satisfactory description of the liquid phase in the Fe��C��Si system has been obtained. The C��Mn��Si system was assessed treating the liquid phase as a substitutional solution. Phase equilibria in the C��Mn��Si system, especially those involving the liquid phase, can be well described. Based on the extrapolation of the experimental data in the quaternary system, the Fe��Mn��Si system has been modified to agree well with experimental data at high temperatures. The comparison between the calculated and measured phase transformation temperatures confirms the reliability of the present quaternary database. Additionally, the solidification process of Fe��0��16C��1��5Mn��1��5Si (wt��%) alloy was simulated by using the thermodynamic database developed.
