A novel method for making open cell aluminum foams by powder sintering process

Open cell aluminum foams were made by powder sintering process. A space-holder method used carbamide to produce samples with porosities between 50% and 80%. The results showed that spherical-shaped pores were obtained depending on the shape and size distribution of the space-holder and the compressi...

Zusammenfassung:Open cell aluminum foams were made by powder sintering process. A space-holder method used carbamide to produce samples with porosities between 50% and 80%. The results showed that spherical-shaped pores were obtained depending on the shape and size distribution of the space-holder and the compressive strength was in agreement with the theoretical relationship for the normalized yield strength.
