Composite material comprising aluminum nitride (AlN) material, less than 80 weight percent cubic boron nitride (cBN) grains dispersed within the AlN material and less that 5 weight percent sinter promotion material, the composite material including no more than about 1.5 percent porosity.

Composite material, articles comprising same and method for making same

A method for making a treated super-hard structure, the method including providing a super-hard structure comprising super-hard material selected from polycrystalline cubic boron nitride (PCBN) material or thermally stable polycrystalline diamond (PCD) material; subjecting the super-hard structure to heat treatment at a treatment temperature of greater than 700 degrees centigrade at a treatment pressure at which the super-hard material is not thermodynamically stable, for a treatment period of at least about 5 minutes to produce the treated super-hard structure.
