摘要：

Aluminium foams were produced by expanding multiple pieces of foamable precursor inside a mould instead of using a single piece. The kinetics of foam formation and mould filling were visualised in situ by X-ray radioscopy. It was found that foaming of multiple precursor materials leads to the best result when the growth directions of the individual precursor pieces are perpendicular to each other. X-ray tomography was used to study the internal structure of the foams in 3D. High local densities in joining regions and in areas of delayed pore nucleation were observed. (C) 2013 Elsevier B.V.
