Abstract: Aluminum foams were successfully prepared by a powder metallurgy method with commercially pure Al powder, Mg powder and TiH2 powder as raw materials. The effects of cold uniaxial compacting pressures on cell structures of aluminum foams with fully lubricated dies and the effects of cold/hot compaction and sintering after cold compaction under the pressure 400MPa on the cell structures and quasi-static compressibility of aluminum foams were both investigated via a scanner with the resolution of 300dpi, SEM and universal testing machine. The results revealed that the high-quality precursors are available by uniaxial cold compaction under the pressure 400MPa with aluminum foams provided as finish products of uniformly distributed cell structures and identical compressibilities.
