Abstract: Embodiments relate to polycrystalline diamond compacts (“PDCs”) that are less susceptible to liquid metal embrittlement damage due to the use of at least one transition layer between a polycrystalline diamond (“PCD”) layer and a substrate. In an embodiment, a PDC includes a PCD layer, a cemented carbide substrate, and at least one transition layer bonded to the substrate and the PCD layer. The at least one transition layer is formulated with a coefficient of thermal expansion (“CTE”) that is less than a CTE of the substrate and greater than a CTE of the PCD layer. At least a portion of the PCD layer includes diamond grains defining interstitial regions and a metal-solvent catalyst occupying at least a portion of the interstitial regions. The diamond grains and the catalyst collectively exhibit a coercivity of about 115 Oersteds or more and a specific magnetic saturation of about 15 Gauss·cm3/grams or less.

Abstract: In an embodiment, a method of fabricating a polycrystalline diamond compact (“PDC”) includes forming a polycrystalline diamond (“PCD”) table in the presence of a metal-solvent catalyst in a first high-pressure/high-temperature (“HPHT”) process. The PCD table includes bonded diamond grains defining interstitial regions, with the metal-solvent catalyst disposed therein.
