Compressive properties of cellular Mg foams fabricated by melt-foaming method

By using CaCO3 powder as blowing agent and Ca particles as thickening agent, cellular pure Mg foams with homogenous pore structures were fabricated by melt-foaming method. Comparing with the Al/Al alloy foams, the cellular Mg foams possess superior comprehensive mechanical properties. The energy absorption characteristics and the effects of compression behavior on the energy absorption properties for the cellular Mg foams have been investigated and discussed.
