This work gives an overview of the production, properties and industrial applications of metal
foams. First, it classifies the most relevant manufacturing routes and methods. Then, it …

The history of metallic foams and the key innovations that have led to the variety of
processing methods known today are reviewed. It is evident that the idea of foaming metals …

The complex flow of liquid metal in evolving metallic foams is still poorly understood due to
difficulties in studying hot and opaque systems. We apply X-ray tomoscopy–the continuous …

Density-graded aluminum foams were successfully prepared via cooling the foam melts
having not yet grown fully. The effects of TiH 2 content and cooling timing on the density …

X-ray radioscopy enables the in-situ monitoring of metal alloy processes and then gives
access to crucial information on the dynamics of the underlying phenomena. In the last …

We studied microporosity in the metallic matrix of aluminium foams produced by the powder
metallurgical route both with and without application of a blowing agent. Microporosity was …

Porous metals such as foams and sponges are produced by a wide variety of industrially
applied techniques mainly for load bearing and structural applications. Their functional …

The production of closed-cell metallic foams has been of interest to the scientific community
and industry for decades, owing to their unique properties, which include high specific …

Initiation and growth of metal foam is a complex and dynamical process, which is intrinsically
three-dimensional and time-dependent. Tomoscopy–or time-resolved tomography–allows …

The use of X-ray radioscopy for in-situ studies of metal foam formation and evolution is
reviewed. Selected results demonstrate the power of X-ray radioscopy as diagnostic tool for …
