Abstract
In this study, we fabricated a precursor by FSW using ADC12 (Al-Si-Cu alloy) powder and foamed the obtained precursor by optical heating to fabricate the porous aluminum (Al). If ADC12 powder can be used for fabricating the precursor, it is expected that Al waste materials from the manufacturing of industrial products, such as Al cutting scraps, can be used as recycled Al chips, with which the cost of porous Al manufacturing can be reduced. The results demonstrated that ADC12 powder can be consolidated as well as the blowing agent (titanium hydride) and stabilization agent (alumina) powders can be mixed into the consolidated ADC12 by FSW to fabricate precursors at the tool traversing speed v = 10–50 mm/min. In addition, the obtained precursor can be foamed by optical heating. It was also found that the precursor with fewer cracks and defects can be obtained at v = 10, 20, and 30 mm/min versus at v = 40 and 50 mm/min. As a result, porous Al with relatively good pore structures was obtained at v = 10–30 mm/min.
