摘要： Ultra-hard constructions include an ultra-hard body having a first region including a polycrystalline matrix first phase and a second phase material interposed therein. The first region is substantially free of a catalyst material used to form the first phase. The body is formed by removing the catalyst material and then replacing it with the second phase material. A second region is disposed within the body and includes the polycrystalline matrix first phase and a catalyst material used to form the first phase. The second phase material has a thermal characteristic that is more closely matched to the matrix first phase than the catalyst material. The body may be joined to a substrate, and the ultra-hard body may consist entirely of the first region. The second phase material can include non-refractory metals, ceramics, silicon, silicon-containing compounds, diamond, cubic boron nitride, polycrystalline diamond, polycrystalline cubic boron nitride, and mixtures thereof.
