Abstract [en]

A thermodynamic description of the Fe-Mn-Ca-Mg-S system is presented. The compound energy formalism is used to describe all solution phases. This work includes assessments of all quaternary systems as well as the ternary systems Ca-Mg-S, Ca-Mn-S and Mg-Mn-S and the binary Ca-Mn system. The remaining ternary sulphur systems and lower-order systems were taken from previous assessments. The description of the solid phases reproduces the available experimental information well. However, due to lack of experimental data, approximations are used for the liquid in the Ca-Mg-S and Mg-Mn-S systems. The thermodynamic description presented in this work can be used to perform calculations related to sulphides in steels.
