中文摘要：
采用CALPHAD方法对Al-Fe-P三元系进行了热力学评估，并根据相关的实验数据对边际二元系Al-P进行了热力学再优化，Al-Fe和Fe-P边际二元系的热力学参数取自之前的研究并做了局部调整．根据相图数据和热力学数据优化了Al-Fe-P三元系的热力学模型参数，获得了体系中所有相的Gibbs自由能表达式．所得参数之间自洽且能很好地重现Al-Fe-P体系的大部分实验相图信息．通过驱动力判据和本文优化所得的模型参数，从热力学上解释了该体系非晶形成能力与组成之间的关系．
英文摘要：
A critical thermodynamic optimization of the AI-Fe-P ternary system was performed using the CALPHAD method. Among the sub-binary systems in the AI-Fe-P system, the AI-P system was reassessed according to its related experimental information. The thermodynamic descriptions of the AI-Fe and Fe-P binary systems were taken from previous studies with minor modifications. The parameters of the thermodynamic model of the AI-Fe-P ternary system were optimized based on available experimental phase diagram data and thermodynamic properties. One set of consistent parameters of the Gibbs energies of all phases, which can satisfactorily reproduce most of the experimental phase diagram data, was obtained. By employing the driving force criterion with the present thermodynamic description, the experimentally reported composition dependence of the glass-forming ability of the AI-Fe-P system could be explained thermodynamically.
