Control of Deformation Behavior of Aluminum Foam-Filled Tube by Introducing Slit on Pipe2016/11Hangai Yoshihiko;Nakano Yukiko;Utsunomiya Takao;Kuwazuru Osamu;Kitahara Soichiro;Yoshikawa NobuhiroJournal of the Japan Institute of Metals80/ 11, 707-7120021-4876URLThe Japan Institute of Metals&emsp;In this study, compression deformation behavior of aluminum (Al) foam-filled thin-walled steel tubes was controlled by introducing slits on the tube and varying length and number of the slits. The deformation of the foam-filled tubes without slits started from various layers depending on the specimens. In contrast, the deformation of foam-filled tubes with slits started from the layer with a longest slit and largest number of slits, and spread to the layer with shorter slits and smaller number of slits. In addition, it was revealed that introducing of the slits on the tube had no effect on compression properties.<br>
  5. Aluminum Foam-Filled Pipe Using Thin-Wall Aluminum Pipe Fabricated from Plate2016/06Hangai Yoshihiko;Nakano Yukiko;Utsunomiya Takao;Kuwazuru Osamu;Kitahara Soichiro;Yoshikawa NobuhiroJournal of the Japan Institute of Metals80/ 6, 386-3890021-4876URLThe Japan Institute of Metals Thin aluminum (Al) pipes filled with Al foam were fabricated by friction welding. In this study, thin Al pipes were formed from thin Al plates and were welded during the coating of a precursor by friction welding. It was shown that seamless Al foam-filled pipes with a uniform wall thickness can be realized. Compression tests on the Al foam-filled pipes revealed that the welding of the pipes had no effect on the generation of cracks in the pipes and their compression properties.
