This paper reportes the thermodynamic analysis of a Cr–Fe system at different temperatures, which involves calculation of the binary phase diagram, activity curve, Gibbs energy curve, and mole fraction curve at three different elevated temperatures: 2125 K, 2150 K and 2175 K. An induced miscibility gap is observed at a particular concentration. Binary phase diagrams show variations in the alloy with temperature. Gibbs energies of mixing and excess energies at different temperatures are discussed. All thermodynamic calculations were carried out using the Thermo-Calc package (based on CALPHAD) and PBIN database.
