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. Powder metallurgy processing employs lower temperatures and, therefore, reduced diffusion rates with better control of interface reaction kinetics. Powder metallurgy route gives way to three crucial steps: mixing, compaction followed by sintering. Mixing and sintering are two characteristic features which govern the final mechanical properties of the material. The distribution factor is influenced by mixing parameter and the strength factor is dominated by sintering parameter. The distribution factor commands the stress required to move a dislocation across two particles. The strength of the material dictates the performance of the material. The sintering of composites is an imperative issue in the material chemistry industry. The sintering of composites is driven by differen...
