Abstract

Abstract: Phase equilibria in the Si-rich domain of the Si-Fe system have been reassessed based on the recent DTA experimental results. Thermodynamic properties of liquid phase have been reassessed using the associated solution model. The properties of DIAMOND_A4 mixture phase have been added in order to evaluate the phase equilibria for the pure silicon materials. The assessed system is able to reproduce the experimental values in the whole composition range of the Si-Fe system.

Key words: Si-Fe, Thermodynamic, Assessment, Phase equilibrium, DTA
