Fabrication of ADC12 porous aluminum by foaming the precursor using a frictional heat

Abstract

In this study, precursor of Al-Si-Cu aluminum alloy ADC12 porous aluminum was foamed only by friction heat of friction stir welding (FSW). The precursor of the ADC12 porous aluminum was also fabricated from die casting aluminum plates by FSW. It was shown that precursor of ADC12 porous aluminum can be foamed using only the heat generated by the friction between the rotating tool and the copper plate.
