Abstract
Young’s modulus for heterophase composite silicon carbide ceramics with different phase ratios has been determined by two independent techniques. The applicability of the Voigt–Reuss–Hill model has been tested to the calculation of the effective Young’s modulus by the measured properties of ceramic components. It is established that the calculated data and results of independent measurements by dynamic indentation are close. It is shown that the advantage of the calculation method is a narrower range of the obtained values of Young’s modulus. At the same time, its application requires additional measurements of ceramic composition and mechanical properties of the components.
