摘要

Three types of cBN-based composites with TaN binder-without whiskers, with Al2O3 whiskers, and with SiC whiskers-have been produced by the high pressure-high temperature (HPHT) sintering. Density, hardness, Poisson ratio, and fracture toughness of the composites have been studied. The whisker-reinforced cBN-based composites exhibit a higher level of mechanical properties (hardness, fracture toughness) in comparison with the non-reinforced materials.
