Notes:
High-energy synchrotron X-ray diffraction is a novel and powerful tool for bulk studies ofmaterials. In this study, it is applied for the investigation of an intermetallic γ-TiAl based alloy. Notonly the diffraction angles, but also the morphology of reflections on the Debye-Scherrer rings areevaluated in order to approach lattice parameters and grain sizes as well as crystallographicrelationships. An in-situ heating cycle from room temperature to 1362 °C has been conducted startingfrom massively transformed γ-TiAl which exhibits high internal stresses. With increasing temperaturethe occurrence of strain relaxation, chemical and phase separation, domain orientations, phasetransitions, recrystallization processes, and subsequent grain growth can be observed. The dataobtained by high-energy synchrotron X-ray diffraction, extremely rich in information, are interpretedstep by step
