The nanomaterials gives opportunity to obtain bulk nanocomposites with better mechanical properties than conventional materials. The aim of this work was to obtain the superhard materials – cBN-TiN nanocomposites and to study them basic mechanical properties. This nanocomposites were sintering under high pressure (7-8 GPa) and high temperature (1400-1800 0C) conditions. The microstructure observations were performed by using scanning electron microscopy (SEM) and also density, chemical phase compositions (XRD) were investigated. Mechanical properties as microhardness and Young`s modulus were determined. The preliminary fabrication processes of these nanocomposites and its results are presented.
