抄録

Super-hard sintered composites in the systems of B₆O-B₄C and B₆O-cBN were prepared by high pressure sintering of composite powders containing in-laboratory synthesized B₆O powder. Nearly fully dense sintered composites were obtained under the high pressure and temperature treatment conditions of 3-6 GPa, 1500-1800°C and 10-30 min. Vickers microhardness of the sintered composites ranged form 3000 to 4600 kg/mm² depending on the composition and sintering conditions. The fracture toughness of the B₆O-cBN system which was higher than that of the B₆O-B₄C system, was observed by the enhanced crack propagation along the grain boundary between B₆O and cBN.
