Processing of open cell aluminum foams with tailored porous morphology

Open cell aluminum foams with tailored porous morphology were synthesized by a space-holder method. Carbamide particles with different shapes were used as a space-holder to produce samples. Depending on the shape distribution of the carbamide particles, the morphology of the pores in the foams can be easily controlled. The foam samples with spherical-shaped pores showed higher compressive strength than those with strip-shaped pores. (c) 2005 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
