摘要： Cutting elements include an ultrahard material body formed at high pressure and high temperature conditions in the absence of catalyzing material to provide a material microstructure comprising a matrix phase of bonded together ultrahard material particles and interstitial regions disposed throughout the matrix phase providing porosity of less than about 6 volume percent. The body may include a substrate attached thereto, and may include an infiltrant material disposed in a population of the interstitial regions. The body may have regions with different porosities, e.g., with a higher porosity region located adjacent a substrate interface and/or along a central region. The body may include more than one infiltrant, each located in different regions. The infiltrant may be introduced into the body during a separate high pressure/high temperature process. The body may include a region which extends a depth from a working surface that is substantially free of any infiltrant.
