Abstract
A hard composite member produced by a rapid omni-directional compaction process that includes the steps of: providing a pre-compaction composite comprising a substrate, a superhard member and a layer of braze between the substrate and the superhard member; placing the pre-compaction composite in a pressure transmitting material contained within a shell to form an isostatic die assembly; heating the isostatic die assembly to a temperature at which the pressure-transmitting material is capable of fluidic flow and wherein the temperature ranges between greater than the melting point of the braze layer and less than or equal to about 1200° C.; and in a forging press, compressing the isostatic die assembly to consolidate the pre-compaction composite under omnidirectional pressure at a pressure equal to or greater than about 60,000 psi into a dense, consolidated body.
