内容記述 |
It is known that the fracture strength was degraded by annealing at low temperature in the neighborhood of 200℃ in yttria doped tetragonal zirconia polycrystals（TZP）and the degradation is caused by the formation of microcracks accompanied with the tetragonal to monoclinic phase transformation. On the other hand, it is expected that the fatigue life-time would increase by the occurrences of microcracks in the neighborhood of main crack. In this study we take a notice of the effect on fatigue life-time of low temperature annealing. Firstly, the degree of tetragonal-to-monoclinic phase transformation were examined by X-ray diffraction for the specimens annealed with various aging times of 20 h to 80 h at respective temperatures of 200℃ and 300℃. Next, the life-times in the cyclic fatigue with a low cyclic load were examined for the specimens annealed by the above method. As the result, it was found that the maximum in the amount of the phase transformation occurred at aging times 40 h in both annealing temperatures and the fatigue life-time somewhat increased with the amount of the phase transformation in the case of 200℃ annealing. |
