    Abstract: Embodiments relate to methods of manufacturing polycrystalline diamond compacts (“PDCs”). In an embodiment, a method of fabricating a PDC includes positioning a plurality of diamond particles adjacent to a cemented carbide material. The cemented carbide material includes one or more types of tungsten-containing eta phases. The method further includes subjecting the plurality of diamond particles and the cemented carbide material to a high-pressure/high-temperature process effective to sinter the plurality of diamond particles so that a polycrystalline diamond table is formed without tungsten carbide grains of the cemented carbide material exhibiting abnormal grain growth that project into the polycrystalline diamond table.

    Abstract: Embodiments of the invention relate to polycrystalline diamond (“PCD”) exhibiting enhanced diamond-to-diamond bonding. In an embodiment, polycrystalline diamond compact (“PDC”) includes a PCD table having a maximum thickness. At least a portion of the PCD table includes a plurality of diamond grains defining a plurality of interstitial regions. A metal-solvent catalyst occupies at least a portion of the plurality of interstitial regions. The plurality of diamond grains and the metal-solvent catalyst collectively exhibit a coercivity of about 115 Oersteds (“Oe”) or more and a specific magnetic saturation of about 15 Gauss·cm3/grams (“G·cm3/g”) or less. The PDC includes a substrate having an interfacial surface that is bonded to the PCD table. The interfacial surface exhibits a substantially planar topography. Other embodiments are directed to methods of forming PCD and PDCs, and various applications for such PCD and PDCs in rotary drill bits, bearing apparatuses, and wire-drawing dies.

    Abstract: Embodiments of systems and methods are disclosed for evaluating a superabrasive material by a three-dimensional model generated using a computed tomography scanner. The model is analyzed to identify a superabrasive matrix within the model and at least one performance characteristic of the superabrasive material is determined according to at least one property of the superabrasive matrix. Methods are also disclosed for characterizing crystal-to-crystal bonding regions and non-superabrasive material within an interstitial matrix of the superabrasive matrix.
