A method for fabricating aluminium foams from powder mixed with foaming agent is presented. Aluminium powder with foaming agent, TiH_2, is compacted and extruded to the die heated by an induction heater. The Al compact including TiH_2 is heated to a temperature more than the liquidus temperature and is extruded into the mold during foaming. The distribution of relative density within the Al foams formed with a pipe is in a range of 0.2 and 0.3 by controlling the pipe temperature. To evaluate the energy absorption of the pipe with the Al foams, a compression test by using a press is conducted. The energy absorbed by the pipe with foams is higher than that by the pipe without foams.
