Abstract

The effects of TiB2 addition to Su3N4 on its mechanical, thermal and microstructural behaviors were investigated. More α-Si3N4 was transformed into β phase with the addition of TiB2 reacted with nitrogen in forming TiN as the hot pressing temperature was increased. The average crack angles in an Si3N4TiB2 composite were generally higher than that for monolithic Si3N4. The toughness of Sin3N4 was substantially enhanced by the incorporation of TiB2 which could not be accounted for by a simple thermal residual stress model.
