Si-C-Ti-O fibers pyrolyzed from polytitanocarbosilane polymer precursors have been observed by a high-resolution transmission electron microscope. Nano-crystalline clusters are finely dispersed in the amorphous matrices of Si-C-Ti-O fibers made from thermal-oxidation-cured and electron-irradiation-cured precursors. Nano-beam electron diffraction and simulated patterns demonstrate that these clusters are β-SiC. Such cluster formation is enhanced in the specimens heat-treated at a high temperature and cured by electron-irradiation.
