Abstract

The microstructure, mechanical properties, fracture behaviour and toughening mechanisms of Al2O3-20 vol% ZrO2(2 mol% Y2O3)-20 vol% SiCWceramic matrix composite were investigated by X-ray diffraction, scanning and transmission electron microscopies, energy dispersive analysis of X-rays, high-resolution electron microscopy techniques and three-point bending tests. The results show that the Al2O3matrix is simultaneously strengthened and toughened by both ZrO2particles and SiC whiskers. The interfacial amorphous layers between SiC whiskers and ZrO2, and Al2O3grains were observed by both TEM dark-field and high-resolution electron microscopy techniques.
