Interphase Oxidation In Sic/Sic Composites
Various high temperature oxidation mechanisms may control the mechanical behavior and failure modes of silicon carbide fiber reinforced, silicon carbide matrix SiC/SiC composites. Interphase oxidation in SiC/SiC composites may occur under different conditions of temperature, oxygen concentration, and interphase thickness. In this work, site specific focused ion beam (FIB) prepared transmission electron microscopy (TEM) specimens of SiC/SiC composites exposed to different oxidation conditions and different sub-critical crack growth conditions have been examined. The microstructural observations provide for direct evidence of proposed high temperature subcritical crack growth failure mechanisms in SiC/SiC composites.
