The Gibbs energies of formation of TiS and Ti4C2S2 in austenite at 1300°C are revaluated from the solubility data measured by Swisher in the Fe-C-S-Ti system. The reevaluation is based on the more realistic assumption that TiS and Ti4C2S2 precipitate as mutually insoluble particles. This is in contrast to the previous analysis, which was based on an ideal solution model of the sulphide and carbosulphide phases. The reevaluated values lead to better agreement with the solubility products measured recently by Yoshinaga et al.
