| Abstract Scope |
Combination of dissimilar AA7075/6060 aluminum alloys benefits the advantages of high strength and good corrosion resistant in one hybrid component. Static compound-casting using appropriate casting conditions can achieve intermetallic bonding at the interface of the core AA7075 and sleeve AA6060. The inhomogeneous bonding due to non-uniform thermal conditions during static compound-casting can be eliminated by the following co-extrusion procedure. Direction hot extrusion of compound-cast AA7075/6060 bilayer billets at temperature of 420°C, 450°C and 480°C are conducted to analysis the influence of extrusion temperature on the interfacial bonding. The evolution of the interfacial bonding properties at different extrusion temperatures comparing with as-cast billets are depicted by light optical metallography and mechanical push-out test. |
