Micromechanical Characterization of Metal Foams
Advanced Engineering Materials, 2019Cellular materials such as foams, honeycombs, or auxetic structures are an interesting type of structural materials for lightweight constructions or dynamic energy absorbers. These microheterogeneous materials consist of a hierarchical structure.

As recently demonstrated, amorphous metal foams are highly ductile in compression, and thus offer attractive compromises in mechanical and physical properties between crystalline metallic and ceramic foams. Challenges associated with fabrication of amorphous metal foams are critically assessed in the context of current and future processing methods ...

Acta Materialia, 2010
Abstract Expansion and contraction phenomena during solidification of liquid metal foams were studied. Such foams were processed by mixing metal powders with TiH2 powder and compacting the resulting blends, after which the compacted powders were melted. The subsequent foaming process was monitored in situ by X-ray radioscopy.

Rheology and Foaming Characteristics of Melt for Metal Foam
Materials Science Forum, 2005Metal foam was produced by the Melt Foaming Method. In this foaming process, the surface tension and the viscosity of molten Al (recycled waste Al) and Mg alloy (Az91) that were measured respectively by the ring method and the rotational method are the most important two factors.
