Wh. Tuan et Wr. Chen, THE INTERACTIONS BETWEEN SILVER AND ZIRCONIA INCLUSIONS AND THEIR EFFECTS ON THE TOUGHENING BEHAVIOR OF AL2O3 (AG+ZRO2) COMPOSITES, Journal of the European Ceramic Society, 14(1), 1994, pp. 37-43
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
