Abstract

Abstract This work presents open-pore metal foams made by investment casting from several pure metals. The resulting microstructure and its morphology will be characterized and compared to the microstructure of permanent mold cast round specimens. In addition to their manufacture, the preparation of the different samples for microstructural characterization is outlined. Finally, the individual microstructures are analyzed and compared by means of light microscopy and under consideration of relevant parameters. The comparison of metal foam and round specimen microstructures yields significant differences in the microstructural development.
