In the present work the influence of nc-TiN nanocrystals on the elastic properties of nc-TiN/a-Si3N4 nanocomposite is discussed. The elastic moduli (shear modulus, compression modulus, Young's modulus) for both amorphous matrix a-Si3N4 and nc-TiN nanocrystals of different size were calculated by first-principles method and molecular static method correspondingly. The Volkov-Stavrov approach was applied for modeling elastic properties of nanocomposite taking into account size and volume fraction of the TiN inclusions. The results of modeling showed the increase the effective elastic moduli of the nc-TiN/a-Si3N4 nanocomposite with nc-TiN inclusions size and volume fraction growth. The obtained results are compared to the experimental data.
