This study aims to fabricate aluminum (A1050)/ duralumin (A2017) multi-layered structures with interface composition gradient by hot rolling, and investigate their nanoindentation properties, and macro-mechanical property such as damping. 2- and 6-layered aluminum/ duralumin graded structures with asymmetric lay-ups from one side of aluminum to another side of duralumin have been fabricated, which suffer from three different heat-treatments such as (1) as-rolled (no heat-treatment), (2) annealed at 400°C and (3) homogenized at 500°C followed by water quenching and aging (T4 heat treatment). Nanoindentation demonstrated higher hardness and elastic modulus correspond to higher Cu content in annealed and aged samples. Duralumin in annealed samples shows much lower hardness and elastic modulus than those in as-rolled and aged ones. For damping properties, 2-layered graded structures show higher values than 6-layered graded structures, which are lower than single layers of aluminum.
