Thermodynamic assessment of the Cr–Mn–O system

The C–Cr–Fe–Ni–O and Fe–Mn–O systems have been studied earlier with the aim to thermodynamically describe the influence of oxygen on high alloyed steels. In this study the ternary Cr–Mn–O system is assessed. The liquid phase is described using the ionic two-sublattice model. Good agreement between calculated and experimental values is achieved.
