Aluminum foam/dense steel composites were fabricated by friction stir welding (FSW). It is expected that both mixing a blowing agent into aluminum and bonding the aluminum precursor to steel can be conducted simultaneously by FSW. It was shown that although heat treatment of the precursor evolved a brittle intermetallic compound layer, the bonding strength of the interface consisting of the intermetallic compound layer was relatively high compared with the fracture strength of the aluminum foam itself.
