Fabrication of uni-pore materials trough explosive compaction using cylindrical geometry

The authors have been investigated the fabrication of uni-directional porous (UniPore) materials through explosive compaction using cylindrical geometry [1-4]. The high-velocity compacting process similar to the explosive welding has been analysed numerically [5] and some advantages of such materials have been demonstrated as heat capacitor [6] and heat exchanger [7]. The authors are going to demonstrate the mechanism of compaction/welding process comparing with the microstructure and the results of compression tests. Some simple 2-dimensional simulated results including the information of collision velocity, in the order of several hundred m/s, are suggested and such velocity enables to achieve metal jet, a kind of fluidized phenomena, which is recognized that the welding mechanism is based on the explosive welding. Also, some potential applications of the UniPore materials are demonstrated at the time of the presentation.
