The compressive behaviors of AZ31-Zr foams using Ca particles as thickening agent and CaCO3 powder as foaming agent were investigated in this study. The porosity was about 48.7%~72.9%, pore size was between 0.43~0.97 mm, and homogenous pore structures were obtained. Mechanical properties of AZ31 Mg alloy foams were investigated by means of UTM. The cellular AZ31 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 AZ31 Mg foams have been investigated and discussed. The results show that with the addition of Zr, the Mg alloy foam has the highest energy absorption value of 16.26 MJ/m3 and the hardness value of 81.8 HV, which is much higher than that of the foams fabricated without Zr.

The static and dynamic compressive behaviors of open-cell aluminum alloy foams with virtually the same relative density of 0.4 were investigated. The foams have different cell sizes (0.5mm, 1.5mm, 2.5mm) but similar cell morphology and microstructure. The yield strength of these foams was characterized as a function of strain rate and cell morphology. The experimental results indicated that the mechanical responses of foams are sensitive to strain rate, and dependent of the cell size. The present results are compared in details with recent findings obtained from the aluminum foams.

Open-cell Zn-22Al foams with different porosities were fabricated by replication process using spheroidal CaCl2 particles as space holder. A series of compressive tests were carried out at different temperatures (i.e., room temperature, 100 °C and 200 °C). The effect of porosity and testing temperature on compressive property and energy absorption characteristic of Zn-22Al foams were studied. The experimental results showed that the compressive properties of the foams are dependent on porosity and testing temperature: the compressive yield stress decreases with the increasing testing temperature and the porosity; In addition, the energy absorption capacity also decreases with the increasing temperature and porosity; Moreover, Gibson-Ashby model can be used to describe the relationship between relative yield stress and relative density of the foams.
