N2 - Experimental investigation of chromium carbide based Cr3C 2-Ni cermets was conducted using a nanoindentation technique. These ceramic-metal composites consisted of 80% (by weight) of ceramic Cr 3C2 phase and the 20% (by weight) of Ni-based binder phase. The binder phase was either pure nickel or nickel combined with either molybdenum or copper. Six different types of these composites with different compositions of binder phase were studied. Local spatially varying elastic modulus and hardness were measured for these six types of composites using the nanoindentation in two modes: manual and automated. In the manual tests, various phases and interfaces were identified by image scans and the nanoindentation data was collected. In the automated tests, the measurements were done in randomly selected regions at fixed distances from each other. This allowed us to compile the statistical data on the distribution and the magnitudes of local elastic moduli and hardnesses. This study gives the information on the spatial heterogeneity in local material properties of these composites. The collected data can serve as input for modeling of these composites and can serve as a useful guide to processing engineers.
