ULTRA-HARD CONSTRUCTIONS WITH ENHANCED SECOND PHASE |
摘要 |
An ultra-hard construction is disclosed that is prepared by a method comprising the steps of treating a material microstructure having a polycrystalline matrix first phase material and a second phase material from at least a partial region of the material microstructure, wherein the second phase material is disposed within interstitial regions of the material microstructure, and wherein removal of the second phase material creates a porous material microstructure characterized by a plurality of empty voids and replacing the removed second phase material with a replacement material having a thermal characteristic that more closely matched polycrystalline matrix first phase that the second phase material.
