Abstract

Based on the available experimental data reported in the literature, the La–Co and Ce–Co binary systems were re-assessed thermodynamically using the CALPHAD method in this work. The calculated phase diagrams and thermodynamic properties of the La–Co and Ce–Co binary systems are well consistent with the experimental results. Furthermore, the La–Co–Fe and Ce–Co–Fe ternary systems were calculated by combining the re-assessed La–Co and Ce–Co binary systems in this work with the previous assessments of the La–Fe, Ce–Fe and Co–Fe binary systems. The calculated liquidus projections, isothermal sections and vertical sections in the La–Co–Fe and Ce–Co–Fe ternary systems are in good agreement with the experimental results. The reasonable thermodynamic parameters of the La–Co–Fe and Ce–Co–Fe ternary systems were obtained in this work, which would be fundamental to developing a thermodynamic database of the multi-component RE-TM-Fe alloy systems, and then to designing novel RE2Fe17-xTMx magnets with light rare-earth metals La and Ce.

La-Co-Fe 和 Ce-Co-Fe 三元体系的热力学描述
根据文献报道的现有实验数据,本研究采用 CALPHAD 方法对 La-Co 和 Ce-Co 二元体系进行了热力学重新评估。计算得出的 La-Co 和 Ce-Co 二元体系的相图和热力学性质与实验结果完全一致。此外,通过将本研究中重新评估的 La-Co 和 Ce-Co 二元体系与之前评估的 La-Fe、Ce-Fe 和 Co-Fe 二元体系相结合,计算出了 La-Co-Fe 和 Ce-Co-Fe 三元体系。计算得出的 La-Co-Fe 和 Ce-Co-Fe 三元体系的液相投影、等温截面和垂直截面与实验结果十分吻合。本研究获得了La-Co-Fe和Ce-Co-Fe三元体系的合理热力学参数,这对于建立多组分RE-TM-Fe合金体系的热力学数据库,进而设计出含有轻稀土金属La和Ce的新型RE2Fe17-xTMx磁体具有基础性意义。

期刊介绍: The design of industrial processes requires reliable thermodynamic data. CALPHAD (Computer Coupling of Phase Diagrams and Thermochemistry) aims to promote computational thermodynamics through development of models to represent thermodynamic properties for various phases which permit prediction of properties of multicomponent systems from those of binary and ternary subsystems, critical assessment of data and their incorporation into self-consistent databases, development of software to optimize and derive thermodynamic parameters and the development and use of databanks for calculations to improve understanding of various industrial and technological processes. This work is disseminated through the CALPHAD journal and its annual conference.
