Abstract
An anvil for use in ultra high pressure presses capable of operating in the pressure ranges where diamonds, polycrystalline diamond composites and cubic boron nitride are stable, fabricated by diffusion bonding together a plurality of cemented tungsten carbide layers. The anvil has a working layer adjacent to the highest pressure of the press with the remaining plurality of layers behind the working layer for support. The working layer has a higher hardness than the supporting layers and the supporting layers each have higher toughness than the working layer.
