High-resolution measurements of mechanical properties are of immense importance in the design of new composite materials. Measuring the intrinsic properties of each phase separately in multiphase composites gives information on the spatial heterogeneity of their local properties and serves as a guide to process engineering and to the design of advanced materials. In this study, the nanoindentation, X-ray analysis, and microstructural SEM investigations have been used to reveal the properties and structural features of ceramic-metal composites - chromium-carbide-based cermets. The semiellipse method for the account of pileups has been applied to this multiphase material to determine the hardness and elastic modulus of the constituent phases. After reconsideration of the contact area, the properties of the phases showed a good agreement with published data. Finally, the measured local elastic properties were used as inputs for modeling the effective elastic response of these materials, and a very good agreement with experimental results was found.
