Foam Structure Effect on the Compression Behavior of Foamed Aluminum Alloy
The effect of the foam structure on the compression behavior of an A–Si–Mg alloy foam, which was produced by a liquid metal method was experimentally investigated. The compressive stress–strain behavior is discussed due to the deformation of a cell within the foam. It is found that the foam with an 81.3 % porosity has both a higher energy absorption capacity and a higher efficiency. The compressive strength decrease as the porosity increases. Experimental result showed that the low compressive strength is attributed to cells imperfection due to the higher porosity.
