Reinforcement Effect of Nano Fe 3 O 4 and Nb 2 Al on the Mechanical and Physical Properties of Cu-Al Based Composites

In the present work, Copper-Aluminium based composites(CAMCs) were designed through 3 different manufacturing processes; “Sintering, “Sinter + Forging” and also “sinter + thixoforming” was made a pre alloy from pure electrolytic copper that was doped with atomized recycled aluminium alloy chips (AA7075) that was given by French Aeronautical Society. After that, a typical composite was created by adding nano magnetic iron oxide (Fe3O4) with a special treatment. Nb2Al intermetallic was also used as reinforcements to increase the wear resistance of the final structure. Graphene Nano Plates (GNPs) and nickel were also added to the CAMCs structures to improve mechanical behaviour and wear resistance of these novel composites. The addition of hard ceramic and/or intermetallic particles to soft copper matrix can significantly improve the mechanical properties and wear resistance, without any serious deteriorating of both magnetic, thermal and electrical conductivities of copper based composites.
