Deformation processing techniques (cold rolling, extrusion and drawing) are used as main manufacturing methods at both industrial and laboratory level—especially for metallic components. Cold working triggers several microstructural phenomena which eventually assist strain-induced strengthening. Recently, deformation processing has extended from conventional strengthening method to a strategic step in fabrication of state-of-the-art modern composites. For example, the in situ synthesis of new improved phases using powder metallurgy requires the powder particles to be arranged in a favorable position, so that the phase synthesis could initiate. This study investigates the codeformation aspects of ceramic (B4C, 1-7 µm) and metallic (Fe, 45 µm) microparticle mixtures (Fe-5, 10 and 15 vol.% B4C), when they are subjected to cold rolling (η = 0.82, 1.24, 1.79, 2.10 and 3.10). While on the one side the inter-particle physical interactions are complemented upon, a methodology is also developed for dealing with deformation-induced microstructural phenomena of the powder mixtures. Results showed that while cold working induces irreversible morphological changes in the Fe particles, the presence of B4C ceramic particles becomes significant only at higher deformation levels.
