Abstract
⺠Hi-Nicalonâ¢/SiC-B4C ceramic composite with a self-healing matrix exhibits good fatigue performance at 1200 °C in air. ⺠The loading frequency has minimal effect on the fatigue performance of Hi-Nicalonâ¢/SiC-B4C at 1200 °C in air. ⺠At 1200 °C, the presence of steam has little influence on the fatigue performance of the composite at 1.0 Hz, but noticeably degrades fatigue lifetimes at 0.1 Hz. ⺠Fiber degradation during fatigue is not caused by oxidation, but is due to an intrinsic creep-controlled flaw growth mechanism. ⺠The fatigue performance of the Hi-N/SiC-B4C composite is controlled by the creep resistance of the Hi-Nicalon⢠fibers.
