Gamma (TiAl-based) alloys possess attractive attributes for structural applications. Adjustment of materials chemistry and processing conditions has been a common practice during materials development to achieve desired microstructure and properties. Traditional approaches relying on pure experimentation and trial-and-error are no longer viable due to limited resources, and materials design processes can be greatly accelerated with the aid of modeling tools. CALPHAD (stands for CALculation of PHAse Diagram), which emerged first as an approach for calculating complex phase diagrams, has now been applied to a broader field of materials science and engineering. This approach plays an important role in ICME. In this presentation, we will demonstrate how we use this approach to develop a thermodynamic database of the Ti-Al-Cr-Mo-Nb-B system. By using this database and Pandat software, we can obtain the phase stability and related properties of TNM and 48-2-2 alloys. Such information is valuable in aiding gamma-TiAl alloy design.
