308 部分安定化ジルコニアの疲労特性に及ぼすアニールの影響(GS3 疲労・破壊(1),研究討論セッション)
詳細
The fatigue behavior of partially stabilized zirconia added to 3 mol % Y_2_O3 was studied with reference to the tetragonal-to-monoclinic phase transformation by static and cyclic fatigue tests for both the specimens annealed at 200℃ for 10hr in air and that at 700℃ for 10hr in vacuum, respectively. As the results, both the higher fatigue strength and the higher crack growth resistance can be obtained by the anneal at 700℃ for 10hr in vacuum, whereas the remarkable degradation in the lifetime by cyclic loading was also observed.
