“…are used in low melting point metals, on the other hand CaCO3, SrCO3, MgCO3 etc. are used in high melting point base metals [60]. The other parameters like stirring time, rpm, holding time, particle size of blowing agent, percentage inclusion of thickening agent also play significant role in production of close cell metal foam.…”

Selection of blowing agent for metal foam production: A review

Metal foams are cellular solids in which gas is uniformly distributed throughout the metal matrix. One of the cheapest ways of evolving the gas is introducing the blowing agent in parent metal in liquid state. A blowing agent is defined as a material that decomposes under the presence of heat and releases gas which then propels the foaming process. The quality of final foam is influenced by several parameters such as composition, size and volume fraction of the blowing agent used. Different chemicals which can evolve gases such as carbonates and metal hydrides fit into the description of blowing agent. Hydrides during decomposition releases H2 gas while carbonates release CO2 or CO gases which are responsible for foaming process. To produce good quality metal foam, the blowing agent must be a compound that does not detriment the foam metallic matrix and must have decomposition temperature closed to the melting point of the metal. This review paper covers the manufacturing processes which uses blowing agent in the formation of metal foam. Furthermore, the paper provides the detail information about the foaming physics, blowing agentâ€™s type and selection criteria of blowing agents to produce amorphous metal foam.

Metallic foam is a popular topic due to its diverse industrial applications and unique combination of properties. Metallic foam is significantly lighter than nonfoam metal materials due to its porous structure, which incorporates a substantial amount of air or voids. This lower density makes metallic foam advantageous in applications in which weight reduction is critical. This makes it ideal for the aerospace, automotive, and construction industries; also, its versatile nature continues to make it an attractive material for various industrial applications such as impact absorbers, heat exchangers, and biomedical and marine engineering. However, the choice between metallic foam and nonfoam metal also depends on other factors like mechanical properties, cost, and specific application requirements. This review describes various fabrication methods of metallic foam that include the liquid metallurgy route which uses liquid or semiliquid metal, the powder metallurgy route uses metal in powder form, metal ion, and the metal vapor route which uses electrolytic deposition method to produce metallic foam. These methods include direct gas injection, adding blowing agents in solid or liquid metals, investment casting, the addition of a space holder in the precursor, metallic ion, vapor deposition on a polymer sponge, and many more. The morphology of metallic foam depends upon the method that is chosen for fabrication, and up to 98% porosity can be achieved by these methods. Additive manufacturing for metallic foam fabrication is an emerging field based on selective laser melting and electron beam melting principles. It has exceptional possibilities for generating complicated 3D shapes and customizing the material characteristics. The main purpose of this review article is to give significant insights into the various production procedures for metallic foams to researchers, engineers, and industry experts, assisting in the selection of acceptable methods depending on individual application needs. This review investigates the manufacturing conditions for metallic foams and finally discusses their advantages, drawbacks, and obstacles in mass production. The findings add to current efforts to expand metallic foam technology and encourage its wider application across diverse sectors, opening the path for future research and development.

“…Applications of metal foams are now found in several areas, such as the Buonomo et al, 2022;Sunder Sharma et al, 2022), building construction (Salimon et al, 2005;Bisht et al, 2019;Farhadi et al, 2020;Chibani et al, 2021;Song et al, 2021), aerospace (García-Moreno, 2016;Murugesan and Mansuri, 2018;Zhu et al, 2018;Madhavan et al, 2019;Liu et al, 2022) and chemical industry (Sajid Hossain and Shabani, 2015;Allioux et al, 2020;Du et al, 2020;Hu et al, 2021;Chen et al, 2023), bio-medical (Singh et al, 2013;Maimouni et al, 2020;Tong et al, 2020;Alavi et al, 2021;Rodriguez-Contreras et al, 2021), energy storage (Lafdi et al, 2008;Huang et al, 2019;Lei et al, 2021;Galvagnini et al, 2022;MERT et al, 2022), the list not being exhaustive. The uptake from the industry is still low though, due to relatively costly scaling production issues and the absence of reliable mechanical property evaluation.…”

Due to their mechanical properties, metal foams are used in various fields. The aim of the present research is to collect different studies about the important mechanical properties of metal foams, such as Young’s modulus, tensile and shear strength, relative density, etc. under tensile and shear loading. Gaps were identified in the methodological embodiments of the experiments due to the use of different standards, as well as in the calculation of mechanical properties through mathematical relations in tensile and shear, which led to deviations between the experimental results and these. Furthermore, this work records sequences and connections between experimental results of different tasks as well as solutions to the aforementioned issues.
