摘要： Ultrahard composite constructions comprise a plurality of first phases dispersed within a matrix second phase, wherein each can comprise an ultrahard material including PCD, PcBN, and mixtures thereof. The constructions are formed from a plurality of granules that are combined and sintered at HP/HT conditions. The granules include a core surrounded by a shell and both are formed from an ultrahard material or precursor comprising an ultrahard constituent for forming the ultrahard material. When sintered, the cores form the plurality of first phases, and the shells form at least a portion of the second phase. The ultrahard material used to form the granule core may have an amount of ultrahard constituent different from that used to form the granule shell to provide desired different properties. The ultrahard constituent in the granule core and shell can have approximately the same particle size.

摘要： Thermally stable ultra-hard compact constructions of this invention comprise an ultra-hard material body that includes a thermally stable region positioned adjacent a surface of the body. The thermally stable region is formed from consolidated materials that are thermally stable at temperatures greater than about 750° C. The thermally stable region can occupy a partial portion of or the entire ultra-hard material body. The ultra-hard material body can comprise a composite of separate ultra-hard material elements that each form different regions of the body, at least one of the regions being thermally stable. The ultra-hard material body is attached to a desired substrate, an intermediate material is interposed between the body and the substrate, and the intermediate material joins the substrate and body together by high pressure/high temperature process.

摘要： A method for manufacturing an ultrahard compact includes assembling a mass of ultrahard material with a mass of substrate material such that the mass of ultrahard material extends radially outward a greater extent than the substrate material to compensate for a difference in the radial shrinkage of the ultrahard material compared to the substrate material during a sintering process. The method may further includes subjecting the assembled compact to a high pressure high temperature process mat results in the forming of an ultrahard compact including an ultrahard layer integrally bonded with a substrate.
