“…Pure metals and varieties of their alloys are used for the manufacturing of metal foams [10,11,12,13]. Among the various open-cell metal foams with high thermal/electrical conductivity and liquid/gas permeability, aluminum foams have emerged as promising material in areas such as heat exchangers, filters, catalyst carriers, and electrodes in aluminum-air batteries due to low cost, relatively easy manufacturing of required functional geometries, and better mechanical properties compared to other low melting metals [14,15,16,17,18,19].…”

Open-cell aluminum foams were manufactured by a sponge replication technique having a total porosity of ~90%. The influence of the thermal processing conditions such as atmosphere and temperature on the cellular structure, phase composition porosity, thermal conductivity, and compressive strength of the foams was studied. It was found that the thermal processing of aluminum foams in Ar at temperatures up to 800 °C led to aluminum foams with a reduced strut porosity, a lower amount of aluminum oxide, a higher thermal conductivity, and a higher compression strength, compared to foams thermally processed in air. These results were explained by the lower amount of aluminum oxide after thermal processing of the foams.

“…Porosity of steel foam can be controlled, and since it affects mechanical properties of the material, Young's modulus and yield stress can be tuned for specific needs by adjusting the foam porosity [2]. Mutlu et al [3] reported successful manufacturing of Cr-Si-Ni-Mo based steel foams, and Hsu et al produced Ti-7.5Mo alloy metallic foam [4]. These recent developments indicate that increasingly exotic metallic materials are employed in metallic foams.…”

“…The processing techniques used to prepare closed‐cell porous metals include the powder metallurgy method, cenosphere embedding technique, and direct foaming of metals. [ 11–13 ] Among these processing techniques, the powder metallurgy method has been used for manufacturing porous metals of titanium, [ 14–16 ] stainless steel, [ 17,18 ] and steel alloy [ 19–21 ] which have high melting temperatures. An appropriate space holder material is used.…”

High compressive strength closed‐cell porous 17‐4PH precipitation hardening stainless steel with three different porosities (30%, 40%, and 50%, volume percent) was manufactured using a novel pressureless powder space holder method. The compressive strengths of the as‐sintered 17‐4PH stainless steel foam with porosities of 30%, 40%, and 50% are 420, 275, and 187 MPa, respectively. The application of an H900 heat treatment to the as‐sintered porous 17‐4PH stainless steel can effectively improve the compressive strength due to the precipitation of ϵ‐Cu phases. It is shown that with this pressureless powder space holder method, it can efficiently produce closed‐cell porous 17‐4PH stainless steel and control its porosity.
