Abstract
Y-PSZ ceramics containing various amount of Al2O3 were fabricated by injection molding method. The green compacts were debound in heating rate of 1.1×10-3K/s up to 723K for controlled burnout of the organic binder, and were sintered at 1823K for 10.8ks.
Vickers hardness, fracture toughness test and bending test were performed to investigate mechanical properties of ceramic composites at the room-temperature.
Because the mechanical properties of ceramic composites depend severely on their microstructures, we discussed the relationship between mechanical properties, microstructures and residual stresses of ZrO2 phases.
