对Ti-Al体系进行了热力学描述。用三种不同的分析描述描述了Ti-Al体系中出现的三种不同类型的相：化学计量相、无序溶解相和均匀范围内的有序金属间化合物。最小二乘技术被用来优化热力学量的分析描述使用实验数据在文献中可用。计算的相图和热力学函数与文献中经过严格评估的实验数据吻合得很好。
A thermodynamic description of the Ti-Al system has been developed. Three different analytical descriptions were used to describe the three different types of phases occurring in the Ti-Al system: the stoichiometric compounds, the disordered solution phases, and the ordered intermetallic compounds which have homogeneity ranges. A least-squares technique was used to optimize the thermodynamic quantities of the analytical description using experimental data available in the literature. The calculated phase diagram, as well as the thermodynamic functions, agree well with the critically evaluated experimental data from the literature.
