Abstract: Metal matrix composites (MMCs) integrate the ductility of metal and the toughness of ceramic particles. The degree of alliance of metal and ceramics constituents can be quantified in terms of interfacial activity. Cu-Al2O3 p composite materials are extensively used in resistance welding electrode, relay blades, electrical contact support, commutators for helicopter starter motor. Performance and microstructural characteristics of particle reinforced MMCs, depends on the size, shape, volume fraction, spatial distribution of the reinforcement entity and nature of the interfacial bonding. In the present investigation MMCs are prepared by powder blending, compaction followed by conventional sintering. Micro structural assessment of the specimen from SEM micrographs has been carried out. Deformation mechanism dominated by dislocation motion is emphasized comprehensively and critically by changing the reinforcement size (from micro- to nano-size) with a variation of sintering temperature....
