“…[19,22] Electroforming of these materials is a common way to produce a new generation of open-cell metal foams usually manufactured with a single layer of metallic shells including nickel, [23] copper, [24] iron, [25] magnesium, [26] etc. Moreover, different kinds of experimental and computational methods used to investigate the micromechanical, [27][28][29] thermal, [30][31][32][33][34] acoustic, [35][36][37][38] and energy absorption properties of copper and nickel metal foams [39][40][41][42][43][44][45] are studied. The resistance to explosive loads and impact was investigated based on the high energy absorption and dynamic properties of metal foams by Tan et al [46] They measured a significant increase in plastic collapse stress in both subcritical and supercritical speed regimes and found that in the subcritical speed regime translational inertia and to a lesser extent rotational inertia of the cell wall is responsible for the increase in strength rather than shock propagation.…”

Metal foams are one of the unique materials that need more attention in terms of mechanical and microstructural characterizations. In the present study, different kinds of metal foams such as Ni, Cu, and a novel type of multi‐layered metal foams with Ni‐Cu and Cu‐Ni coating layer orders have produced and characterized in terms of mechanical response and microstructure of these novel materials during a uniaxial compression test. These multi‐layered metallic foams have a strong mechanical adhesion at the interface due to the nature of electroforming process and the effect of solid solution area at these interfaces. Besides, Multi‐layered metal foams are superior to Ni and Cu pure metal foams in terms of mechanical response, applying a multi‐layered metallic coat with 60 and 69 μm diameter for Ni and Cu improved the yield point of the Ni and Cu single layer metallic foams for 3 and 7 times, respectively. Moreover, in terms of energy absorption density, the multi‐layered metallic shell has improved the energy absorption density for 3 and 5.5 times compared to Ni and Cu metal foams, respectively. This study shows that applying multi layered coatings to metal foams with Ni as the first layer has superior characteristics compared to single layer metal foams.This article is protected by copyright.
