Preparation and characterization of cBN-based composites from cBN-Ti3AlC2 mixtures
Diamond and Related Materials, 2016Abstract Cubic boron nitride (cBN)-based composites were prepared at ~ 5.5 GPa and ~ 1350 °C with different mass ratios of cBN-Ti3AlC2 mixtures as starting materials. Ti3AlC2 decomposed and reacted with cBN during high pressure and high temperature (HPHT) sintering. TiC, TiC0.7N0.3, TiB2, and AlN were then formed.
