The aluminum alloy foam with varying structural properties was prepared with melt foaming method using titanium hydride as blowing agent. The influence of process parameters were investigated in correlation with the structural properties of foamed aluminum. It is observed that the amount of titanium hydride and the duration of holding time for foaming have significant influence on the final cell structure over other process parameters. The microstructural analysis reveals the presence of intermetallics inside the cell wall and alumina on the pore surface contributing for the stability during foaming process. The mechanical properties and energy absorption capacity were calculated and analyzed, showing direct dependence with relative density of the foam.
