Due to the process, metal foams produced by powder metallurgy have an inhomogeneous pore structure. The pore size variations from a few tenths of a millimeter up to the centimeter range is so typical. This leads to inconstant properties and makes the

The manufacturing processes for sandwiches made with aluminum or steel sheets are differentiated by their various melting ranges. Sandwiches with aluminum face sheets have recently been produced using to the so-called AFS technology, which includes a
Die Werkstoffexoten Holzschaum und Metallschwamm besitzen interessante Eigenschaften, die von denen gebräuchlicher Werkstoffe abweichen. Die Fraunhofer-Institute WKI, IFAM und IWU erzeugen durch das Verschmelzen beider Werkstoffe einen neuartigen Le

Wood foam and metal sponges are exotic materials with interesting properties that deviate from those of conventional materials. By merging both materials, the Fraunhofer Institutes WKI, IFAM and IWU generate a novel, lightweight composite that is sus

The application of the serial sectioning technique for the reconstruction of spatial microstructures is demonstrated using two single phase polycrystalline microstructures as examples. The materials examined are an austenitic steel and a ZnO ceramic.
In the past it has already been proven that aluminum foam is a construction material appropriate for numerous applications. Especially in domains such as machine tool manufacturing and vehicle construction the combination of lightweight design and vi

Fast-moving machine tool assemblies should be light and rigid. Because of the lightweight construction and the dynamic loads these assemblies are very often susceptible to vibrations. Aluminum foam sandwiches are laminates with an aluminum foam core
