摘　　要：Fe-Ti二元系作为多组元Fe合金和多组元Ti合金的子系统,其热力学性质研究是将其拓展到多维应用的基础.利用CALPHAD方法,选取近几十年来最具代表性的5篇Fe-Ti二元系评估研究论文,复现各评估研究的计算结果,比较不同评估对稳定相的热力学建模的相异性和对最终评估结果的影响,同时指出某些评估中存在的问题.As a subsystem of multi-principal-elements Fe alloys and multi-principal-elements Ti alloys,the thermodynamic properties of the Fe-Ti binary system are the basis for expanding it to multi-dimensional applications.By using CALPHAD method,five of the most representative Fe-Ti binary system assessment research articles in recent decades were selected and the calculation conclusions of these research were reproduced.Meanwhile,the dissimilarities of the thermodynamic modeling of stable phases of different assessments and the impact on the final evaluation results were compared,and some problems in the evaluation were pointed out.
