Closed-cell aluminium foams (nominal composition: AlSi12Mg0.6Fe0.3) were prepared by the powder metallurgical route (using 0.4 wt.% TiH2 untreated powder as the foaming agent). Pure foams and foams with the addition of 3 vol.% graphite or SiC powder

The zinc foams were prepared by powder compaction method with various types (TiH2 or MgH2) and various amount (0.3, 0.6 and 1 wt.%) of foaming agent to investigate the effect of colouring of zinc foams during foaming process. It was observed that due

Closed cell aluminium foam samples and panels with phase change material (PCM) infiltrated in vacuum were investigated. The utilization of PCMs in larger volumes is strongly limited because of its low thermal conductivity in liquid state. However, po
