Abstract
A new superhard phase, cubic BC2N, has very recently been synthesized by di rect conversion of graphite-like BN-C solid solutions at 25 GPa and 2100 K. The hardness. Young's modulus, fracture toughness and structure of this ph ase have been examined using micro- and nanoindentation and transmission el ectron microscopy. The hardness and elastic modulus values (E, G) of the c- BC2N are intermediate between diamond and cubic boron nitride. which makes this new phase the hardest known solid after diamond.
