Imaging tools are great instruments for materials
development. New hardware developments provide enough spatial and time
resolution for in-situ analysis. Imaging with X-ray and neutrons
provides a way to study qualitatively and quantitatively processes in
materials science.
Metallic foams are very attractive
materials due to their exceptional properties and their industrial
relevance. Their analysis and further development needs in-situ
methods for the observation of their expansion evolution and
macroscopic pore structure. Investigations with photons and neutrons
are exceptional instruments for these analyses.
