Metal-matrix composites (MMCs) are usually characterized by soft matrix and hard reinforcement. In contrast, we focused in this work on the production and properties of metastable MMCs formed by pure Ag matrix and pure Cu particulates. To conserve the metastable character of these MMCs, they were produced by spark plasma sintering of the Cu@Ag core-shell powders with the volume ratios Cu:Ag being 55:45 and 82:18. These m-MMCs exhibit specific mechanical properties. Some of them, Young modulus and the shape of the curves of plastic deformation, are discussed in this work.
