Abstract

Thermodynamic property of solid MnS-CrS-FeS system was determined based on the combination between thermodynamic properties of liquid MnS-FeS, CrS-FeS, and MnS-CrS-FeS phase determined by the authors and reported phase diagram of MnS-FeS, CrS-FeS and MnS-CrS system. The determined parameters were verified by comparison with experimental results of equilibrium relationship between metal/sulfide in Fe-Cr-Mn-S system at 1 793 K. By utilizing the determined parameters, phase equilibria involving sulfide phase in liquid Fe-Cr-Mn-S system was established. According to the phase equilibria information, controllability of MnS-CrS-FeS sulfide phase in typical stainless steel during solidification was evaluated.
