摘要：

The Gibbs energies of formation of TiS and Ti4C2S2 from Ti, S and C solutes in austenite are evaluated on the basis of the solubility data measured by Swisher in the Fe-C-S-Ti system. These quantities are employed in equilibrium calculations applied to a series of Ti bearing steels. The results indicate that Ti4C2S2 is expected to predominate in Ti micro-alloyed steels, whereas both TiS and Ti4C2S2 are likely to be present in Ti modified extra-low-carbon IF steels. These predictions are in good agreement with the experimental observations reported by other researchers. © 1990, The Iron and Steel Institute of Japan. All rights reserved.
