Summary

In this paper, attention is focused on how changes can occur in the structure of a foam while the cell wall material is fluid.

Material redistribution during foam processing can lead to cell coarsening, density gradient build-up or even to disintegration of the foam structure. In this work a model is presented describing material redistribution during processing of metallic foams. The model allows quantitative evaluation of the effects of the geometrical characteristics of the foam and the key physical properties of the material on the way that the foam structure evolves. Predictions obtained from the model are compared with experimental results obtained on aqueous foams. Implications of the results for production of metallic foams are briefly discussed.
