Only within the last couple of years, complete isothermal sections for the Al-Ti-Zr system have been determined. Up to then there had been several investigations, but these were limited to the Ti-Zr and Ti-Al sides and the Ti- and Al corners of the system. Also recently the system has been evaluated by thermodynamic ab initio calculations and CALPHAD-type (CALculation of PHAse Diagrams) modelling. As Al-Ti-Zr alloys are of interest for a variety of applications and as the last assessment has been performed more than 15 years ago, this new critical evaluation of the existing literature about phase equilibria in the Al-Ti-Zr system has been performed.

铝钛锆系统的关键评估

仅在最近几年，才确定了 Al-Ti-Zr 系统的完整等温截面。到那时已经进行了多次调查，但仅限于系统的 Ti-Zr 和 Ti-Al 侧以及 Ti-和 Al 角。最近，该系统还通过热力学 ab initio 计算和 CALPHAD 型（PHA 酶图计算）建模进行了评估。由于 Al-Ti-Zr 合金具有广泛的应用前景，而且上一次评估是在 15 年前进行的，因此对现有关于 Al-Ti-Zr 系统相平衡的文献进行了新的批判性评估。执行。
