Aluminium foams were created on ground and under microgravity conditions and were allowed to evolve. The entire foaming process was monitored by in situ X-ray radioscopy, allowing for flow and drainage of the liquid of the foam to be monitored and quantified. A foam with a known low stability level was used to enhance the effects of microgravity. The flow of metal out of the foam under gravity during the 1.8 g phase was found to be fast, indicating a mobile liquid. The density profile evolved in a similar way as in aqueous foams. Reentry of the liquid melt into the foam was also observed. Under microgravity the foam re-established a uniform density and pore size distribution after nearly complete imbibition of the liquid. This also shows that the liquid is mobile.
