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.
