    Abstract: Embodiments of the invention relate to polycrystalline diamond (“PCD”) exhibiting enhanced diamond-to-diamond bonding. In an embodiment, PCD 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. Other embodiments are directed to polycrystalline diamond compacts (“PDCs”) employing such PCD, 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: Methods of manufacturing sintered superabrasive structures are disclosed. For example, a plurality of agglomerated granules comprising at least one superabrasive material may be provided and exposed to a pressure and a temperature sufficient to sinter the at least one superabrasive material. In another example, a plurality of agglomerated granules comprising diamond may be provided and exposed to a pressure and a temperature sufficient to form polycrystalline diamond. Articles of manufacture including at least one superabrasive material are disclosed. For example, a polycrystalline diamond compact may comprise a volume of polycrystalline diamond bonded to a substrate, wherein the volume of polycrystalline diamond includes a plurality of agglomerated granules which have been sintered. A drill bit comprising at least one cutting element including a volume of polycrystalline diamond bonded to a substrate wherein the volume of polycrystalline diamond includes a plurality of agglomerated granules which have been sintered is disclosed.

    Abstract: Some embodiments relate to cutting element assemblies including a superabrasive cutting element that may be axially compressed to enhance the damage tolerance thereof, enclosed in an enclosure that exposes the superabrasive cutting element therethrough, enclosed in an enclosure that restricts rotation of the superabrasive cutting element, or combinations of the foregoing. Additionally, some embodiments relate to cutting element assemblies in which a superabrasive cutting element is mechanically fastened to a base, such as a substrate or directly to a bit body of a rotary drill bit. Some embodiments also relate to cutting element assemblies including one or more superabrasive cutting elements that are rotatable about a longitudinal axis of the cutting element assembly, that may be axially compressed to enhance the damage tolerance thereof, that may be enclosed in an enclosure that exposes the superabrasive cutting element therethrough, or combinations thereof.
