## Description

- description: Although SiC fibers are promising reinforcement materials for applications
    in high-temperature environments, the effects of heating on the thermomechanical
    and thermoelectrical properties of these fibers have not been discussed and correlated
    with the associated microstructural changes. To bridge this gap, we herein in
    situ monitored the elastic modulus and electrical conductivity changes accompanying
    the conversion of single amorphous Si–Al–C–O fibers to Si–Al–C polycrystalline
    fibers during heating to up to 1900 °C in vacuum using an in-house-built device.
    The weight and tensile strength changes due to heating at 1200–1900 °C in vacuum
    were correlated with the concomitant fiber crystallinity and microstructural changes.
    The mechanical and electrical properties of the fibers were related to the porous
    structure formed by the decomposition of the amorphous SiCxOy phase, rigid structure
    bonded by nanograin sintering–induced grain growth, and carbon layer formed by
    Si sublimation from the fiber surface.
