Steel–magnesium composites with various volume fractions of Mg were processed to investigate the potentiality of such metal matrix composite for the design of light weight multi-metallic materials. The composites were obtained by co-extrusion at room temperature of Mg powders inserted in steel jackets. During the first step of the process the steel jacket diameter is decreased by a factor of ten leading to a strong compaction and deformation of the original Mg powder particles. A fully dense material is then achieved by annealing. Composites with various architectures and length scales were also obtained by restacking the material in other steel jackets and subsequent extrusion passes. This presentation will focus on the influence of the Mg volume fraction on the co-deformation mechanisms and on the relationship between the composite structures and the mechanical properties.
