“…In the automobilistic industry, for instance, polyamide is widely employed in different parts of a car once it can be easily processed and has low cost. Besides, the replacement is convenient once it reduces the weight of the vehicle, making it more efficient and less polluting [1].…”

“…It is also becoming widely recognised that the future of automotive production will be based on a multi-materials approach, allowing more efficient use to be made of the best attributes of different classes of materials [2][3][4]. This will inevitably result in a greater need to join dissimilar combinations of metals, including aluminium and magnesium alloys.…”

a b s t r a c tHigh power ultrasonic spot welding (USW) is a low heat input solid-state joining process that may offer a solution for welding difficult dissimilar-material couples, like magnesium (Mg) to aluminium (Al) for automotive body applications. However, the high strain rate dynamic deformation in USW has been claimed to accelerate inter-diffusion rates in dissimilar joints. The interfacial reaction between Al, AA6111, and Mg AZ31 alloys has been studied as a function of welding energy. For the optimum welding condition of 600 J (0.4 s) the reaction layer thickness was already $ 5 mm thick. Intermetallic reaction centres were found to nucleate within microwelds at the interface at very short welding times and spread and grow rapidly to form a continuous layer, composed of two sub-layers of Al 12 Mg 17 and Al 3 Mg 2 . Interface liquation was also found for longer welding times at temperatures below the recognised lowest eutectic reaction temperature in the Al-Mg binary system. Modelling has been used to show that the solid state reaction kinetics were over twice the rate expected from parabolic growth predictions made using rate constants obtained under static test conditions. The reasons for this discrepancy and the depressed melting reaction are discussed.

“…Two approaches can be distinguished in this context. First, multi-material systems describe the combination of different materials at component level [27]. Examples of these include the so-called "Erlanger beam" (in this structure a thin-walled aluminium structure is reinforced with a FRP component) and circular CFRP rib construction [26].…”
