PRECIPITATE-STRENGTHENED HARD METAL-DIAMOND COMPOSITE
A cutting table for a cutting element, including: a diamond phase; a tungsten carbide phase; a cobalt-tungsten metallic phase; and an intermetallic phase comprising Co3WCx, where 0≤x≤1. Also disclosed is a method of manufacturing a cutting element, the method including: sintering diamond and tungsten carbide particles in the presence of Co and W to about 1520° C. or greater under pressure of about 57 kbar or greater to form a hard metal-diamond composite compact and solubilize carbon and tungsten within the compact; cooling the cutting element at about 1° C./sec or greater; and subsequent to cooling the cutting element, heat-treating the cutting element to precipitate carbon and tungsten in the compact as an intermetallic phase.
