摘要：

The mechanical properties and the phase stability in yttria and ceria stabilized zirconia containing 0-20wt% Al2O3 during aging in air (300 degrees C) and in water vapor (150 degrees C, 180 degrees C, 200 degrees C and 250 degrees C) are investigated in this paper. It is found that water can greatly accelerate the degradation of Y-Ce-TZP. The addition of Al2O3 to Y-Ce-TZP prevents the low temperature degradation in air. Also Al2O3 particles can restrain the phase transformation of tetragonal to monoclinic in Y-Ce-TZP under water vapor condition when the temperature is below 200 degrees C.
