Abstract

Embodiments of the invention relate to polycrystalline diamond compacts (“PDCs”) including a pre-sintered polycrystalline diamond (“PCD”) table that may exhibit a non-cylindrical-shaped geometry and/or may have been partially graphitized prior to bonding to a substrate in a high-pressure/high-temperature process (“HPHT”). The disclosed PDCs may be used in a variety of applications, such as rotary drill bits, mining tools, drill bits, bearing apparatuses, wire-drawing dies, machining equipment, and other articles and apparatuses.
