摘要：

3 mol% Y2O3-stabilized Tetragonal Zirconia Polycrystals (Y-TZP) reinforced with 15% vol. Al2O3 platelets have been deformed in compression at constant strain rates between 10(-5) and 2 x 10(-3) s(-1) and temperatures between 1250 and 1400 degrees C. The composites have been found to behave in a similar way to monolithic Y-TZP. The strain rate controlling mechanism is characterized by a stress exponent n of 2, the deformation being achieved by grain boundary sliding. No increase in the creep resistance due to platelet-reinforcement was found because of the high ductility of the zirconia matrix.
