摘要

Ti-Al-V 合金因其出色的高温机械性能而备受关注。在对 Ti-Al-V 三元体系的现有实验数据进行严格审查后,利用 CALPHAD 方法对该体系的整个成分和宽温度范围进行了热力学评估。结果令人满意地再现了 α2 和 γ 相的广泛均匀性范围。这项研究获得的模型参数很好地代表了实验数据的热化学性质和相平衡。此外,本研究中建立的热力学描述还再现了广泛使用的钛合金 Ti-6Al-4V 的焓。因此,本研究为指导 Ti-Al-V 合金的开发和设计提供了可靠的依据。

Thermodynamic modeling of the Ti–Al–V system over the entire composition and a wide temperature range

Ti–Al–V alloys have received considerable attention owing to their excellent high-temperature mechanical properties. After conducting a critical review of the available experimental data for the ternary Ti–Al–V system, a thermodynamic assessment of the system was carried out over the entire composition and a wide temperature range utilizing the CALPHAD method. The extensive homogeneity ranges of the α2 and γ phases were satisfactorily reproduced. Of particular significance was the first accurate description of the phase equilibria at 1573 K. The model parameters obtained in this study well represented the thermochemical properties and phase equilibria of the experimental data. Furthermore, the enthalpies of the widely used Ti alloy Ti–6Al–4V were reproduced using the thermodynamic description established in this study. Thus, this study provides a reliable basis for guiding the development and design of Ti–Al–V alloys.

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.
