Abstract: This research studied the fabrication method for open-cell aluminum foams by replication
process which was based on pressure infiltration and salt leaching method. Melting process was
studied at temperature range of 600-750°C. Four different sizes; 22, 13, 10 and 6 mm of Australian
salt were used as space holders for the replication method. The experiment was carried out in a tightly
closed stainless steel mold and argon gas pressure at 1.5 bar was applied during infiltration process.
This research investigated suitable temperature for fabricating aluminum foams from commercially
pure aluminum (99.7%Al) and ADC12 aluminum alloy (85.5%Al-10%Si-1.8%Cu). The study showed
suitable temperatures for the melting process of pure aluminum foams at 725°C and ADC12 at 650°C.
Aluminum foams fabricated in this study had interconnected strut network with % open porosity
varied in the range 55-70%. |
