“…The use of foams as cores in metallic sandwiches [9,10] and the use of net-shape stainless steel reinforcements can increase the mechanical response in bending/tension [11], as well as in compression [12]. However, the inconveniences of these approaches are the weight payload and the extra manufacturing costs.…”

Present research work evaluates the influence of both density and size on the treatability of Aluminum-based (6000 series) foam-parts subjected to a typical solid solution heat treatment (water quenching). The results are compared with those obtained for the bulk alloy, evaluating the fulfilment of cooling requirements. Density of the foams was modeled by tomography analysis and the thermal properties calculated, based on validated density-scaled models. With this basis, cooling velocity maps during water quenching were predicted by finite element modeling (FEM) in which boundary conditions were obtained by solving the inverse heat conduction problem. Simulations under such conditions have been validated experimentally. Obtained results address incomplete matrix hardening for foam-parts bigger than 70 mm in diameter with a density below 650 kg/m 3 . An excellent agreement has been found in between the predicted cooling maps and final measured microhardness profiles.

Sandwich panels consisting of a highly porous aluminium foam core and aluminium alloy face sheets are manufactured by roll‐bonding aluminium alloy sheets to a densified mixture of metal powders – usually Al‐Si or Al‐Si‐Cu alloys with 6–8% Si and 3–10% Cu – and titanium hydride, and foaming the resulting three‐layer structure by a thermal treatment. We review the various processing steps of aluminium foam sandwich (AFS) and the metallurgical processes during foaming, compare the process to alternative ways to manufacture AFS, e.g. by adhesive bonding, and give an overview of the available literature. Two ways to treat AFS after foaming are presented, namely forging and age‐hardening. Some current and potential applications are described and the market potential of AFS is assessed.

“…However, the compressive strength of aluminum foams alone is too low to use as a load bearing material. Therefore, most aluminum foams are used as aluminum foam sandwich components or aluminum foam-filled tubes (Seeliger, 2002). However, there are some problems with panel and tube structures.…”
