Abstract:
1. A diamond bonded construction comprising: a diamond body comprising a matrix phase of intercrystalline bonded diamond, and a plurality of interstitial regions dispersed within the matrix phase; a metallic substrate attached to the diamond body; and a metallic support attached to the substrate; wherein the substrate and support each comprise a carbide-containing material, wherein the support has a material composition that is different from that of the substrate prior to sintering of the diamond body, and wherein a first population of the interstitial regions contain a catalyst material disposed therein provided from the metallic substrate and used to form the diamond body at high pressure/high temperature conditions, and wherein a second population of the interstitial regions are free of the catalyst material.
