Fabrication of unidirectional porous-structured aluminum through explosive compaction using cylindrical geometry

A method for fabricating an unidirectional porous (UniPore) aluminum structure employing a cylindrical explosive compaction assembly is proposed and the condition for successful recovery is discussed. The microstructure of the compacted samples is demonstrated to show tight bonding between the walls with uniform pores oriented in one direction. The compacting process is numerically simulated by the Autodyn code and the results are in a good agreement with the experimental results. The results of compression tests showing a plateau region are also demonstrated.
