Abstract
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.
Highlights
In view of applications, different parts of the Al-Ti-Zr system are of interest and investigation of phase equilibria over the decades reflects these interests

Summary
Different parts of the Al-Ti-Zr system are of interest and investigation of phase equilibria over the decades reflects these interests. The key for any aimed alloy development is a sound knowledge of phase equilibria in dependence of temperature and composition. In this regard, assessments play an important role as they collect all the available evidence and critically evaluate it. (2020) 41:687–701 activities of MSIT are inextricably associated with Gunter Effenberg and his awareness of the importance of phase diagrams, thermodynamic and crystallographic data. This assessment is dedicated in memory of him
