摘要： Embodiments of the invention relate to non-cylindrical polycrystalline diamond compacts (“PDCs”), and methods of fabricating such non-cylindrical PDCs without substantially undercutting a cemented carbide substrate thereof from an overlying polycrystalline diamond (“PCD”) table thereof. According to various embodiments, a PDC includes a PCD table including an upper surface and a table non-cylindrical lateral periphery. The PDC includes a cemented carbide substrate bonded to the PCD table. In an embodiment, the cemented carbide substrate includes a substrate non-cylindrical lateral periphery that is not substantially undercut from the table non-cylindrical lateral periphery of the PCD table. In an embodiment, the PDC includes at least one alignment feature positioned on the cemented carbide substrate and/or the PCD table.

摘要： 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.
