Abstract
The synthesis of high-purity bulk nanostructured cubic boron nitride (cBN) at 20 GPa and 1770 K by direct phase transformation of graphite-like BN with an "ideal random layer" structure is reported. The two-times increase of hardness of nano-cBN (H(V) = 85 GPa) with respect to conventional polycrystalline cBN (H(V) ∼ 45 GPa) is evidently a result of nanosize effects.Entities:
