| Abstract: | Open pore aluminum foams were made by powder sintering process and the compressive behavior was studied. Carbamide and NaCI powders were used as space holders to produce samples with porosity of 70% . The results show that pores with spherical, angular or strip shape are obtained depending on the shape and size distribution of the space- holder and it is also possible to obtain a purposely tailored distribution of relative density in the foams by varying the weight fraction of the aluminum powders in the sintered compact. The compressive strength of the aluminum foams is affected by the pore morphology. All the foam samples of spherical shape pores show higher compressive strength as compared with these of angular and strip shape pores. |
