Effect of Alloying on Compressive Mechanical Properties of Aluminum Foam Alloy
Several open-cell aluminum foams were prepared by alloying with Si, Mg and Cu elements. The effects of the alloying treatment on their compressive mechanical behavior and energy absorption characteristic were investigated by guasi-static compressive experiments. The results show that the stress-strain response and the energy absorption of the aluminum foams are affected remarkably by the addition of the alloying elements such as Si, Mg and Cu, and the yield strength as well as energy absorption property of the foams improve greatly.
