Abstract

The binary phase diagram of the Fe-Se system was modelled by the thermodynamic CALPHAD approach for the first time. The thermodynamic description of this system was mainly based on the available experimental isobaric molar heat capacity of the Fe1.042Se (β) phase in the temperature range of 25–777 °C and on the published proposed experimental phase diagrams. The formation enthalpies of Fe1.042Se (β), Fe7Se8, Fe3Se4, FeSe (δ) and FeSe2 phases at 25 °C were also implemented into the phase diagram modelling. Magnetic properties of the Fe3Se4 (γ) phase were theoretically calculated by ab initio methods and implemented in the assessment.
