Abstract

The present work reported the effect of addition of ZrO₂ on the microstructure and mechanical properties of ZrB₂-based ceramic composites by means of hot-pressed sintering. Observation of microstructure and systematic testing results of mechanical properties were carried out. Through X-ray diffraction analysis and calculation of the volume fraction of ZrO₂ phase transformability, the toughening mechanism of the present composites was explored. The phase transformation toughening by ZrO₂ additive played an important role in improving the fracture toughness of ZrB₂ -based composites.
