Superhard constructions & methods of making same
A superhard polycrystalline construction comprises a body of polycrystalline superhard material formed of a mass of superhard grains exhibiting inter-granular bonding and defining a plurality of interstitial regions therebetween, and a non-superhard phase at least partially filling a plurality of the interstitial regions and having an associated shape factor of greater than around 0.65 and a substrate bonded to the body of superhard material along an interface, the substrate having a region adjacent the interface comprising hinder material in an amount at least 5% less than the remainder of the substrate.
