Abstract

The effects of post-foaming thermal processing on the quasi-static compressive strength of closed-cell aluminium foam with an average relative density of 0.56 g/cc have been investigated. Samples were subject to one of four material conditions: as-received (AR), warm aged (WA), solution treated (ST), and annealed (AT). X-ray diffraction (XRD ) was performed to determine a relationship between each material condition and macro-crystallographic texture of the dendritic α-Al phase. It was found that all heat treated samples contained clear deviations from random texture towards the exterior regions of the samples, indicating non-uniform recrystallization kinetics. The ST and WA samples exhibited the highest yield stresses and energy absorption , with the AT samples exhibiting the lowest. Additionally, it was found that the AR and WA conditions lost 12.8 and 15.6% of their total mass from brittle cell wall crumbling, whereas the AT and ST conditions lost 2.5 and 3.0% of their total mass.
