Characterisation of SiC/Ti composites using 3D X-ray tomography

Scientific Case

Metal Matrix Composites (MMCs) have been explored for wider applications in the field of engineering for the past three decades. The unique properties such as higher specific strength/stiffness and lower density which are not possible by conventional materials can be achieved through MMCs. Reinforcements/matrix interface play a critical role in determining the mechanical performances, especially during the work conditions, such as fatigue, tension, creep, etc. Reinforcements and matrix are interconnected and interactive at such interfaces, so characterisation of the interfaces has been significantly focused on for the past three decades in order that more understanding could be achieved in the improvement of MMC technologies. In this experiment, the characterisation of the intact SiC/Ti sample will be undertaken so that more knowledge of the macro-structure and micro-structure would be gained for the composites.

Experiment Design

Interfaces of composites: W-SiC and SiC-Ti; the diameters of precursor fiber W and SiC fiber are 15 μm and 100μm, respectively.
