Preparation and microstructure of TiB2-TiC-SiC platelet-reinforced ceramics by reactive hot-pressing

Using TiH2, Si and B4C as raw materials, a platelet-reinforced ceramic composite of TiB2-TiC-SiC was prepared by reactive hot-pressing. The product has three phases: TiB2 (in plate-like shape), TiC and beta-SiC. The microstructural characteristics of the composite were observed by SEM and the phase...

Zusammenfassung:Using TiH2, Si and B4C as raw materials, a platelet-reinforced ceramic composite of TiB2-TiC-SiC was prepared by reactive hot-pressing. The product has three phases: TiB2 (in plate-like shape), TiC and beta-SiC. The microstructural characteristics of the composite were observed by SEM and the phase chemistry was analysed by EDX. The mechanical properties of the composite were also determined. 13 refs.
