Abstract Blending of lamellae grains with other organic elements is the basic feature of biological nacre material to demonstrate its highest strength. Reconstruction of these hierarchical structures with combinations of metallic lamellae grains is a challenge of the day which is trending in the field of bioinspired structural materials. Such nanolaminated aluminum alloy based metallic nanocomposites are processed through addition of graphene using powder metallurgy route followed by hot extrusion. Intervallicre-nucleation to achieve lamellae grains in the nanocomposites by addition of graphene significantly enhanced the mechanical properties like micro-hardness and strength of the prepared nanocomposites.
