AbstractLarge AlO-SiC and AlO-SiC-TiC composites disks (150 mm diameter) were prepared in this work by using the spark plasma sintering technique. The main physical and mechanical properties of these composites were measured in different disk zones in order to test out the homogeneity of the sintering process. It has been found that the incorporation of TiC as reinforcing phase to the AlO-SiC composite, improved densification, mechanical strength and hardness. This result was analyzed in terms of SEM microstructure observations showing that the presence of TiC inhibited the alumina grain growth.
