| Abstract: | Based on compression tests of SiC granular reinforced Al foams made by PM route measured,mchanical properties and energy absorption capability had been investigated.Compressive stress-strain curve consists of three distinct regions.: the linear elasticity region,the plastic collapse region,the densification region.With the increase of the volume fraction of SiC particles,the compressive yielding strength under compression were greatly improved. |
