Abstract

The synthesis of diamond-SiC nanocomposites with enhanced fracture toughness was investigated. The synthesis was based on high-energy ball milling to form amorphous Si precursors which were followed by rapid reactive sintering at high pressure (P) and temperature (T). The P-T application allow control of reactive sintering of nanocrystalline SiC matrix in which diamond crystals were embedded. The synthetic technique presented opportunities to design and develop superhard composite materials with strong nanocrystalline bonding matrix with improved fracture toughness and thermal stability.
