Summary

Metallic foams were produced applying the powder compact method, i.e., by mixing powdered metals and a foaming agent and subsequently pressing the mixture to a foamable precursor material. This precursor material is then foamed by heating it up to its melting point. The expansion of the foamable precursor material and its temperature were monitored during the entire foaming process by means of a laser sensor and a thermocouple, respectively. The influence of some of the manufacturing parameters on the expansion behaviour of aluminium alloys was investigated. Besides the foaming kinetics the evolution of morphology (shape and size of the cellular pores) during the foaming process is discussed.
