Abstract
The toughening behaviour of Al2O3/Ag, Al2O3/ZrO2 and Al2O3/(Ag+ZrO2) c omposites has been studied. The toughness increase of the Al2O3/(Ag+Zr O2) composites is less than the sum of the toughness increase of the A l2O3/Ag and of the Al2O3/ZrO2 composites. It results from the interact ions between silver and zirconia inclusions during sintering. In the p resent study the interactions between silver and zirconia inclusions a re examined carefully. The influence of the interactions on the micros tructure development and on the toughening behaviour of the composites is discussed
