N2 - Earlier measurements of elastic moduli of nc-TiN/a-Si3N 4 nanocomposites of different composition and hardness by means of vibrating reed and surface Brillouing scattering, that yield Young's and shear modulus, as well as the Poisson's ratio, have been confirmed by high-pressure X-ray diffraction measurements, that yield bulk modulus. It is found that elastic moduli of all measured samples are essentially the same within relatively small error of measurements, and only slightly lower than that of pure TiN. The nanocomposites are superhard thanks to their unique nanostructure with strengthened SiNx interface.
