The enhancements of the thermomechanical performance of bulk diamond compacts in terms of hardness, fracture toughness, wear resistance, impact strength, and thermal stability are our project objectives. It is to aim at applying an advanced nanosynthesis process for the manufac-turing of superhard and ultratough diamond/SiC nanocomposites with the implementation of nanofiber reinforcement. The R&D re-sults can be used in multi-industrial applications, particularly, for drill bits designed to encounter dynamic impacts for high speed oil/gas drillings, thus to achieve high efficiency and energy saving. Science and technology (S&T) researches on precursors, cata-lyst, reactive sintering, and in-situ/real-time characterization of high P-T neutron/X-ray diffraction studies on phase stability, syn-thesis kinetics, residual strain, and yield strength have been applied to help optimizing the nanomanufacturing process. Our R&D ef-fort in high P-T nanosynthesis of TSP diamond/SiC composites is to achieve superior performance of nanomechanics in resisting dy-namic impact and thermal degradation, while still maintaining the super-hardness and super-abrasiveness of diamond and silicon-car-bide. The improved polycrystalline diamond compact (PDC) bit inserts for drilling, boring, and cutting will be applied in harsh envi-ronments so as to meet the demands of the mining, petroleum, and machinery industries. With success of the proposed project, the expected energy savings and reduction of CO2 emission will be significant and the economic advantages are going to be enormous.展开更多
