Chapter 12 Design of Magnetic Aluminium (AA356) Composites (AMCs) Reinforced with Nano Fe3O4, and Recycled Nickel: Copper Particles L-M. P. Ferreira, E. Bayraktar, I. Miskioglu, and M-H. Robert Abstract New classes of aluminium matrix composites (AMCs – 356) were designed by three different manufacturing techniques; only sintering, through combined method called here after “Sinter +Forging” and/or “sinter +thixoforming”. Main reinforcement was magnetic iron oxide, Fe3O4 (10, 20 and 30 wt %) and two recycled reinforcements, nickel, Ni and pure electrolytic copper, Cu, given by French Aeronautical Society were also used and preceded under the constant process parameters such as hot compaction, sinter-forging, sintering time, Forging temperature and Force, etc. As auxiliary element, hybrid graphene nano-platelets, GNPs, was added in the structure. Microstructural analyses (by using SEM), magnetic, mechanical and physical properties of the composites were compared with three different manufacturing processes. Static compression tests, Micro hardness tests, measurement of magnetic permeability and also electrical conductivity, have shown 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.

These composites are actually used in high-tech structural and functional applications including aerospace, defence, automotive, and thermal management areas. New class of “AMCs” reinforced with nano iron oxide (Fe3O4), hybrid graphene nano-platelets, GNPs (d < 10 nm), Nickel, etc., show good thermal conductivity and also low thermal expansion. For this reason, these composites are categorized as very high multifunctional lightweight materials. The present paper is based on the low cost manufacturing light and efficient materials and using them in engineering applications. For this reason, a comprehensive study has been carried out on the magnetic properties of the AMCs (AA356) reinforced basically with nano Fe3O4-iron oxide and other alloying elements such as hybrid graphene nano-platelets, GNPs, Nickel, etc. In the frame of the research project that is going on. Three different manufacturing techniques were used; only sintering, through combined method called here after “Sinter +Forging” and/or “sinter +thixoforming” with low cost manufacturing of light and efficient multifunctional materials or much more interesting one is multiferroïques composite for aeronautical applications that is one of the aims of the present work.
