Open-cell 4 vol.% SiCp/AlSi9Mg composite foams with different relative densities were fabricated by the infiltration process using NaCl preforms. The distributions of SiC particles in the cell wall were observed and compressive properties and energy absorption characteristic of the foams were investigated. The results show that the yield stress and the energy absorption capacities of open-cell 4 vol.% SiCp/AlSi9Mg composite foams increase with the rising relative density. And the stress-strain curves of open-cell 4 vol.% SiCp/AlSi9Mg composite foams are not as smooth as that of aluminum foams due to the addition of SiC particles. The theory model used to describe the energy absorption capacity of the foams in different strain region was induced. Crown Copyright (C) 2010 Published by Elsevier B.V. All rights reserved.
