摘要：
The effects of sintering temperatures on consolidation and mechanical properties of 3 mol% Y-TZP (3Y-TZP) powders were studied in this work. Samples were sintered at 1250 degrees C to 1450 degrees C sintering temperature in air. Throughout the sintering regime, high value of relative bulk density 99.41% of theoretical densities was obtained for the maximum sintering temperature. Maximum Young's modulus of 3Y-TZP was obtained at 1450 degrees C and maximum fracture toughness value of 3Y-TZP was observed at the 1300 degrees C sintering temperature. The Vickers's hardness values of 3Y-TZP also increased gradually with sintering temperature.
