Experimental results on the synthesis in a cubic apparatus of composites based on diamond-like boron nitride cBN in the cBN-Al-TiC system are presented. It is shown that with an optimal ratio of the number, size and mutual arrangement of particles of a superhard material and a nanostructured binder, it is possible to achieve a high level of properties without the obligatory intergrowth of particles of superhard cBN-cBN crystals with each other. The composites were sintered at a pressure of 4.5 GPa and a temperature of 1450 ° C. The selected thermobaric parameters ensured the completeness of the reaction interaction, the uniformity of the phase composition and physical and mechanical characteristics in the entire volume of large-sized composites.
