Abstract

Functionally graded (FG) aluminum foam consisting of A1050 and A6061 aluminum alloy was fabricated by using friction stir processing (FSP). The fabrication of the precursor and the bonding of the A1050 precursor to the A6061 precursor can both be conducted by FSP. According to the results of point analysis, the Mg content gradually changed in the bonding region, and it was shown that seamless FG aluminum foam can be fabricated by the FSP route.
