Abstract

The PcBN materials were sintered from the cBN-Al systems under high-pressure and high-temperature, and the mechanical properties, composition and microstructure of prepared samples were analyzed. The results show that the microstructure is fairly even and the binding phase is uniformly distributed in its volume. The sintered samples are composed of a large portion of cBN and of a small portion of AlN, also very little amount of AlB2. And cBN grains are always surrounded by AlN and AlB2 layer which formed three-dimensional networks. It also shows that the hardness of the PcBN composites decreases and the density values increase with Al content increasing.
