Abstract: The aim of this research is to develop and characterise square and cylindrical foam filled tubular structures made of aluminium alloys. The thin-walled tubular structures were filled with a closed-cell foam during its in-situ foam formation using the powder metallurgy method. The deformation modes and compressive behaviour were studied using uniaxial compressive tests together with infrared thermography. The results demonstrate that the in-situ foam filled tubular structures have strong bonding and a high ductility that contributes to a progressive and stable axisymmetric deformation under compressive loads without the formation of cracks.
