摘要：

A thermodynamic assessment of the Ti-Mo-C-N quaternary system has been made based on the previous assessments of the Ti-C-N and Mo-C-N systems in combination with new assessments of the Ti-Mo-C and Ti-Mo-N systems. The parameters of the thermodynamic models describing the individual phases of the quaternary system were evaluated from experimental information in the literature through a computer-aided optimization technique called the CALPHAD method. The thermodynamic parameters were used to calculate phase diagrams and to evaluate thermodynamic stability of the (Ti, Mo)(C, N) phase of the quaternary system. The calculated results were in good agreement with experimental results. (C) 1999 Published by Elsevier Science S.A.
