    摘要： Embodiments of the invention relate to polycrystalline diamond compacts (“PDCs”) comprising a preformed polycrystalline diamond (“PCD”) table including a thermally-stable region having a copper-containing material disposed interstitially between bonded diamond grains thereof, and methods of fabricating such PDCs. In an embodiment, a PDC includes a substrate, and a preformed PCD table having an interfacial surface bonded to the substrate and a generally opposing upper surface. The PCD table includes a plurality of diamond grains exhibiting diamond-to-diamond bonding therebetween and defining a plurality of interstitial regions. The preformed PCD table further includes a first region extending inwardly from the upper surface that includes a copper-containing material disposed therein and a second region extending inwardly from the interfacial surface that includes a nickel-containing material disposed therein.

    摘要： Embodiments relate to polycrystalline diamond compacts (“PDCs”) including a polycrystalline diamond (“PCD”) table in which a metal-solvent catalyst is alloyed with at least one alloying element to improve thermal stability of the PCD table. In an embodiment, a PDC includes a substrate and a PCD table bonded to the substrate. The PCD table includes diamond grains defining interstitial regions. The PCD table includes an alloy comprising at least one Group VIII metal and at least one metallic alloying element that lowers a temperature at which melting of the at least one Group VIII metal begins. The alloy includes one or more solid solution phases comprising the at least one Group VIII metal and the at least one metallic alloying element and one or more intermediate compounds comprising the at least one Group VIII metal and the at least one metallic alloying element.
