摘要：

Evaluation of thermodynamic parameters of the Cr-C and Cr-Ni-C systems has been made by using sublattice models. The Gibbs energies of formation of Cr23C6, Cr7C3, and Cr3C2 were reassessed from the experimental data. The interaction between chromium and carbon in the nickel-rich face-centered cubic (fcc) phase of the ternary Cr-Ni-C system and the Gibbs energies of formation of metastable Ni23C6 and Ni7C3 in the binary Ni-C system have been estimated from the experimental data of the ternary Cr-Ni-C alloys. The assessments were carried out simultaneously by using a computerized optimization technique. The thermodynamic parameters optimized in the present work are able to reproduce appropriately the experimental results in the Cr-C and Cr-Ni-C systems. © 1990 The Metallurgical of Society of AIME.
