Microstructure and Mechanical Properties of ZrB 2 ‐Based Composites Reinforced and Toughened by Zirconia
Source abstract
Abstract
The present work reported the effect of addition of ZrO 2 on the microstructure and mechanical properties of ZrB 2 ‐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 ZrO 2 phase transformability, the toughening mechanism of the present composites was explored. The phase transformation toughening by ZrO 2 additive played an important role in improving the fracture toughness of ZrB 2 ‐based composites.
