“…After decades of research, aluminum foams with different alloy compositions have been fabricated. For example, MF pure Al [36], Al-Cu [145], Al-Mn [146], Al-Zn [147], Al-Sc [142] systems, GIF Al-Si-Mg [57], Al-Si-Cu [56] systems, PMF Al-Si [84], Al-Si-Cu [85], Al-Mg-Si [86], Al-Sn [87], and Al-Si-Mg-Cu-Sn [88] systems. Heat treatment [145,148,149], matrix composite [150][151][152], and other methods have been used for strengthening.…”

Closed-cell aluminum foams have many excellent properties, such as low density, high specific strength, great energy absorption, good sound absorption, electromagnetic shielding, heat and flame insulation, etc. As a new kind of material, closed-cell aluminum foams have been used in lightweight structures, traffic collision protections, sound absorption walls, building decorations, and many other places. In this paper, the recent progress of closed-cell aluminum foams, on fabrication techniques, including the melt foaming method, gas injection foaming method, and powder metallurgy foaming method, and on processing techniques, including powder metallurgy foaming process, two-step foaming process, cast foaming process, gas injection foaming process, mold pressing process, and integral foaming process, are summarized. Properties and applications of closed-cell aluminum foams are discussed based on the mechanical properties and physical properties separately. Special focuses are made on the newly developed cast-forming process for complex 3D parts and the improvement of mechanical properties by the development of small pore size foam fabrication and modification of cell wall microstructures.

“…The compressive strength of foams increased with the addition of reinforcements and the presence of a well-defined porous structure. This indicates the feasibility of these fabrication techniques for the development of metallic foams [ 65 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 ].…”

“…Some of the common foaming agents and injection gases include TiH 2 [ 101 , 102 , 103 , 104 , 105 ], CaCO 3 [ 106 , 107 ], zirconium hydride [ 108 , 109 ], dolomite (CaMg(CO 3 ) 2 ) [ 110 , 111 ], etc. The stabilising particles such as Ca, ZrB 2 , CaO, Al 2 O 3 , etc., are also added into the melt [ 83 , 112 ]. The melt is then stirred continuously for the foaming agent and stabilizing particles to distribute evenly.…”

Metal foams possess remarkable properties, such as lightweight, high compressive strength, lower specific weight, high stiffness, and high energy absorption. These properties make them highly desirable for many engineering applications, including lightweight materials, energy-absorption devices for aerospace and automotive industries, etc. For such potential applications, it is essential to understand the mechanical behaviour of these foams. Producing metal foams is a highly challenging task due to the coexistence of solid, liquid, and gaseous phases at different temperatures. Although numerous techniques are available for producing metal foams, fabricating foamed metal still suffers from imperfections and inconsistencies. Thus, a good understanding of various processing techniques and properties of the resulting foams is essential to improve the foam quality. This review discussed the types of metal foams available in the market and their properties, providing an overview of the production techniques involved and the contribution of metal foams to various applications. This review also discussed the challenges in foam fabrications and proposed several solutions to address these problems.
