Effect of pore size and relative density on the mechanical properties of open cell aluminum foams

Abstract

Reproducibility and predictability of pore size and relative density of open cell aluminum foams with spherical pores synthesized by the space-holder method have been studied and mechanical properties of the foam were investigated in light of its pore size and relative density. The results showed that the reproducibility and predictability of the compressive property and the control precision of relative density were improved with decreasing pore size. The compressive stress–strain curve increased with a increase in pore size and relative density.
