    Abstract: In an embodiment, a method of fabricating a polycrystalline diamond compact is disclosed. The method includes sintering a plurality of diamond particles in the presence of a metal-solvent catalyst to form a polycrystalline diamond body; leaching the polycrystalline diamond body to at least partially remove the metal-solvent catalyst therefrom, thereby forming an at least partially leached polycrystalline diamond body; and subjecting an assembly of the at least partially leached polycrystalline diamond body and a cemented carbide substrate to a high-pressure/high-temperature process at a pressure to infiltrate the at least partially leached polycrystalline diamond body with an infiltrant. The pressure of the high-pressure/high-temperature process is less than that employed in the act of sintering of the plurality of diamond particles.

    Abstract: Embodiments of methods are disclosed for characterizing a tested superabrasive element, such as a polycrystalline diamond element. In an embodiment, a method of characterizing the relative strength of a superabrasive element is disclosed. A first superabrasive element and a second superabrasive element are positioned upper surface to upper surface, including an area of overlap between the upper surfaces. A load is applied while the first and second superabrasive elements are overlapped until failure of one or both of the first or second superabrasive elements fail. A relative strength is determined using at least the load during failure as a parameter.
