摘要： Embodiments relate to methods of fabricating PCD materials by subjecting a mixture that exhibits a broad diamond particle size distribution to a HPHT process, PCD materials so-formed, and PDCs including a polycrystalline diamond table comprising such PCD materials. In an embodiment, a method includes subjecting a mixture to heat and pressure sufficient to form a PCD material. The mixture comprises a plurality of diamond particles exhibiting a diamond particle size distribution characterized, in part, by a parameter θ that is less than about 1.0, where θ = x 6 · σ , x is the average particle size of the diamond particle size distribution, and σ is the standard deviation of the diamond particle size distribution. In an embodiment, the diamond particle size distribution can be generally modeled by the following equation: CPFT 100 = D n - D S n D L n - D S n , wherein CPFT is the cumulative percent finer than, D is diamond grain size, DL is the largest-sized diamond grain, DS is the smallest-sized diamond grain, and n is a distribution modulus.

摘要： Fully dense, diamond-silicon carbide composites are prepared from ball-milled microcrystalline diamond/amorphous silicon powder mixture. The ball-milled powder is sintered (P=5–8 GPa, T=1400K–2300K) to form composites having high fracture toughness. A composite made at 5 GPa/1673K had a measured fracture toughness of 12 MPa·m1/2. By contrast, liquid infiltration of silicon into diamond powder at 5 GPa/1673K produces a composite with higher hardness but lower fracture toughness. X-ray diffraction patterns and Raman spectra indicate that amorphous silicon is partially transformed into nanocrystalline silicon at 5 GPa/873K, and nanocrystalline silicon carbide forms at higher temperatures.
