Thermal treatment effects on the microstructure and mechanical response of Hi-Nicalon SiC fibers
Original language description
This study focuses on the gates the mechanical behaviour of silicon carbide (SiC) fibres previously subjected to heat treatment temperature (HTT) between 1000 and 1500 °C. Nanoindentation techniques were employed to assess local mechanical properties, including hardness and elastic modulus, while scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to investigate microstructural changes. The results reveal a significant reduction in hardness and elastic modulus with increasing HTT, attributed to phase transformations and microstructural changes. A non-uniform degradation pattern was observed, with the fibre core deteriorating more rapidly than the skin.These findings offer key insights into the thermomechanical stability of SiC fibres, crucial for enhancing their performance in demanding environments, especially in aerospace applications. Understanding their degradation mechanisms aids in optimizing their mechanical and thermal properties.
