In this work, aluminium matrix composites (AMCs with scrap A356 powder given by French Aeronautical Society) were designed through combined method of powder metallurgy and thixoforming (sinter + Forging). Three different reinforcements (Magnetic iron oxide, Fe3O4 – Hybrid graphene nano-platelets, GNPs, Nickel, Ni) were used and preceded under the constant process parameters such as hot compaction, sinter-forging, sintering time, etc. Mechanical and physical properties of the composites were improved with the combined processing method of powder compacted specimens and reinforcement volume fractions. Static compression tests, Microhardness tests, surface scratch tests, measurement of magnetic permeability showed that the mechanical and physical properties of these composites can be improved with the optimization of process parameters. In the present work, an alternative and a low cost manufacturing process were proposed for these composites. The microstructure and damage analyses have been carried out by Scanning Electron Microscope (SEM).
