基于 ab Mina 计算的 Fe7C3 和 Fe23C6 吉布斯能的最新数据的可用性需要对 Fe-Cr-C 系统中的热力学参数进行彻底的重新评估。为了执行优化过程，对 Fe-Cr-C 系统的实验文献数据进行了详细的关键评估。这项工作中应用了使用计算机优化程序 (PARROT) 的 Calphad 技术。因此，基于详细的文献调查，本工作获得了 Fe-Cr-C 体系的新的自洽热力学描述。结果以多个相图的形式呈现。 (C) 2014 Elsevier Ltd. 保留所有权利。
The availability of recent data on Gibbs energies of Fe7C3 and Fe23C6 based on ab Mina calculations required the complete reassessment of the thermodynamic parameters in the Fe-Cr-C system. In order to perform the optimization process a detailed critical evaluation of the experimental literature data on the Fe-Cr-C system was made. The Calphad technique using a computerized optimization procedure (PARROT) was applied in the work. Thus, a new self-consistent thermodynamic description of the Fe-Cr-C system based on a detailed literature survey was obtained in the present work. The results are presented in a number of phase diagrams. (C) 2014 Elsevier Ltd. All rights reserved.
