Superhard constructions & methods of making same

摘要

A super hard polycrystalline construction comprising (i) a body of polycrystalline super hard material having a super hard phase with (ii) inter-bonded grains having interstitial spaces there between in which is dispersed a non-super hard phase and where (iii) the non-super hard phase occupies substantially 3-5 volume % of the total volume of the construction.
