在室温下，用450keV C+离子辐照了两种类型的碳化硅纤维，一种是低氧富碳纤维601-4，另一种是低氧近化学计量比碳纤维SA。拉曼光谱表明，辐照使纤维中的碳化硅微晶发生变形和非晶化。Tyranno SA的透射电子显微镜表征表明，碳化硅微晶继续碎裂成较小的晶岛，周围的非晶态结构继续增加。碳化硅纳米晶(
Two types of SiC fibers, one is low-oxygen and carbon-rich fiber denoted by 601-4 and the other is lowoxygen and near-stoichiometric Tyranno SA, were irradiated with 450 keV C+ ions at room temperature. The Raman spectra indicate that irradiation induced distortion and amorphization of SiC crystallites in fibers. TEM characterization of Tyranno SA suggests that SiC crystallites undergo a continued fragmentation into smaller crystalline islands and a continued increase of surrounding amorphous structure. The SiC nano-crystallites (
