| Abstract: | Microstructure, grain growth and fracture toughness of alumina-zirconia composites prepared from commercial grade technical alumina" and imported zirconia were studied. Ostwald ripening and coalescence of ZrO2 and AI2O3 grains were observed. Fracture toughness of the composites having different phase assemblages seemed to be controlled by the transformation toughening and microcracking toughening mechanisms. Highest fracture toughness of the 'Order of 5.5 MN m-3/2 was found for the composite prepared from a batch of AI2O3 + 29.5% ZrO2 + 1.5% Y2O3. |
