Environmental Effects on Microstructural Stability of SiC/SiC Composites
Abstract： Environmental effects, especially O2 pressure, often make SiC/SiC composites degraded. In order to investigate the effects on microstructural stability, SiC/SiC composite specimens, made of Hi-NicalonTM SiC fibers, were annealed under a commercial grade Ar flow and an ultra-high purified Ar flow respectively. The microstructural evolution in SiC/SiC composites was examined by a field emission type high-resolution electron microscopy and a parallel electron energy loss spectroscopy. A possible mechanism for this degradation was discussed. 作 者： Tamaki Shibayama Guo Wei He Heishichiro Takahashi Yutai Katoh Akira Kohyama 作者单位： Tamaki Shibayama,Guo Wei He,Heishichiro Takahashi(Center for Advanced Research of Energy Technology, Hokkaido University, Sapporo 060-8628, Japan)Yutai Katoh,Akira Kohyama(Institute of Advanced Energy, Kyoto University, Gokasho, Uji 611-0011, Japan)
