Cutting elements include a diamond-bonded body attached with a substrate. The substrate has a coercivity of greater than about 200 Oe, and has a magnetic saturation of from about 73 to 90. The diamond-bonded body has a compressive stress at the surface of greater than about 0.9 GPa after heat treatment, and greater than about 1.2 GPa prior to heat treatment.

Cutting elements with impact resistant diamond body

Assemblies as disclosed herein for making superhard products by HPHT process comprise a first can portion for accommodating a mixture of materials therein and a second can mated with the first can portion. A leak-tight seal is provided between the first can portion and second can portion in a manner that accommodates the manufacture of relatively longer superhard products without having to change other elements or members used for HPHT processing to thereby provide improved manufacturing flexibility and cost efficiency.

Assemblies for making superhard products by high pressure/high temperature processing

A method for forming an ultra hard material layer is provided. The method includes disposing a metallic liner inside the periphery of a refractory metal enclosure, introducing ultra hard material feed stock into the enclosure, and sintering using HPHT processing and cooling to form the ultra hard material layer, substantially free of peripheral cracking, chipping and fracturing.

Method for forming ultra hard sintered compacts using metallic peripheral structures in the sintering cell

According to the present invention there is provided a method of making a cutting insert with a hole for clamping to a tool holder wherein a super-hard abrasive material is sintered and simultaneously bonded to a sintered cemented carbide body with a hole inside a container under elevated pressure and temperature conditions. During sintering the hole is filled with a plug which after sintering is removed.
