Electron-beam-cured polycarbosiline fibres were heat-treated at 673-1773K in a tube evacuated to 1.3 x 10-1 Pa and then exposed at 1873K in argon. The effect of vacuum heat treatment on improving the high-temperature stability of low-oxygen SiC fibres was investigated by examining gas evolution, grain growth, surface composition, tensile strength and morphology.
