| Abstract: | A new type multi-components porous Al alloy with high specific strength was fabricated by infiltration method. The deformation behavior and energy absorption property of porous Al alloy were studied under uniaxial compressive loading condition. The influences of uniformity of cell wall, porosity and heat-treatment on properties were investigated. The results showed that the compression and energy absorption property of porous Al alloy were increased significantly by improving the uniformity of cell wall and applying heat-treatment, and the compressive strength can be increased by decreasing porosity of porous Al alloy. |
