Abstract

Gibbs energy modeling for sulfur solving liquid and solid iron–chromium phases with body- and face-centered cubic structure has been carried out using a substitutional approach. Experimental data available from the literature on sulfur potentials in the temperature range 1 525 to 1 755 °C for the liquid metallic phase and 1 000 to 1 300 °C for the solid alloys have been taken into consideration. Recent thermodynamic evaluations of the Fe–S and Cr–S binary subsystems served as basis for the presented work. The obtained models allow a satisfactory reproduction of the majority of the sulfur potential data as well as the prediction of an isothermal partial section at 1 300 °C. Consistent embedding of the optimized Gibbs energies within a recent thermodynamic modeling of the complete Cr–Fe–S system is achieved.

Keywords: Chromium; Iron; Sulfur; Chromium–iron–sulfur system; Solubility; Thermodynamic modeling
