Open cell aluminum foams were synthesized by the space-holder method. NaCl particles as space-holder were used to produce samples. The effect of the Y 2 O 3 , which was added to the aluminum powders on the mechanical properties of the open cell aluminum foams, has been studied. Adding Y 2 O 3 powders in the compacts has important effect on the foams showing better mechanical...
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.
