Abstract
Fine-grained Al2O3-ceramics with TiO2- and ZrO2-additions (AZT) exhibit superior thermal shock performance. Impressive results could be shown using bending tests before and after a thermal shock. The reasons for this behaviour have to be investigated in the microstructure. In the present paper the combined possibilities of X-Ray computed tomography (XCT) and electron backscatter diffraction (EBSD) for characterizing the microstructure of AZT materials are demonstrated.
