Abstract: Young's modulus of composite heterophase SiC-ceramics with different phase ratios is determined on the base of two independent methods. The Voight-Reuss-Hill model is demonstrated to be applicable for calculation of the Young's modulus using measured characteristics of ceramic components. The calculation results are close to the results of independent dynamic indantation measurements. Lower uncertainty of Young's modulus is shown to be the advantage of the calculation method. At the same time, the application of this method requires additional measurements of ceramics composition and mechanical properties of all components.

Keywords: ceramics, silicon carbide, elastic modulus, nanoindentation, dynamic indentation.
