Homogeneously tailored Al2yO3-ZrO2 composites were fabricated using a fibrous monolithic process. The microstructure of the composites was varied depending on the area reduction ratio, and correlated well with calculated data. The sintered bodies presented a continuously fibrous monolithic microstructure and no swelling occurred during the binder burning-out. Microcracks were observed at the Al2O 3ZrO2 interfaces, due to the mismatch of thermal expansion coefficients between Al2O3 and ZrO2 phases. Most of the ZrO2 grains included twin defects to accommodate the stress field during the sintering process.
