Abstract

An aluminum foam sandwich was fabricated by FSP route. In this process, both the fabrication of a foamable precursor and the metallurgical bonding between the precursor and a dense steel sheet can be simultaneously conducted. Although intermetallic compounds consisting of Fe ₂Al ₅ and FeAl ₃ were generated, tensile tests revealed that the bonding strength of the interface was relatively high compared with the tensile strength of the aluminum foam with a porosity of approximately 80%.
