“…Laser heat treatment involves heating a metal part with laser light, increasing its temperature to a point where its crystal structure changes, causing surface hardening or enhanced wear resistance (Hitz et al, 2001). In the case of new materials like metal foams, laser processing such as laser forming, laser welding, laser cutting, and laser additive manufacturing can be applied successfully (Changdar and Chakraborty, 2021).…”

“…These techniques are often preferred in industrial applications due to their easy applicability and low cost (Seeliger, 2002). However, in TIG welding of some foam metals, the filler metal is used to prevent shrinkage and condensation due to melting in the weld area (Changdar and Chakraborty, 2021). These techniques are not suitable for highly porous metallic foams, but suitable for welding AFS part to AFS part or AFS part to aluminum dense sheet (Shirzadi et al, 2004;Seeliger, 2002;Busic et al, 2016).…”

“…In 1996, the use of metallic foams in the automotive industry started with the studies conducted by Karmann Car on the use of aluminum foam sandwich (AFS) structures in automotive body parts (Banhart and Seeliger, 2008). In today, metallic foams are used in some parts of important automotive brands such as BMW, Audi, and Ferrari, but they face some problems during the commercialization phase (Garcia-Moreno, 2016;Changdar and Chakraborty, 2021). One of the most important problems of metallic foams not being widely used is welding (Shirzadi et al, 2004;Smith et al, 2012).…”

“…It may produce low ductility near the joints, especially where porosity is limited as the interparticle bonding zone (Selcuk et al, 2013). The foam structure tends to collapse with rising temperature, so the welding process should be done without any collapse of the foam structure (Changdar and Chakraborty, 2021). The welding of metal foam, in general, is quite complex and involves many factors to be considered.…”

Metallic foams are a new type of material class using in the much-diversified area such as automotive, biomedical, and construction etc. Thanks to its porous structure, it stands out with its energy and impact absorption as well as its lightness. Due to the properties, metal foams have the potential for use in many applications. As the number of uses and potential applications increases, it becomes important to develop adequate joining technologies for metallic foams and to select appropriate methods for their widespread industrial use. However, various problems are encountered in welding metallic foams with a foam or a face sheet. The most important feature that causes differences in the welding process and characteristics of these materials is porosity. While the methods such as MIG/TIG could be preferred in the past, the methods such as laser welding have come to the fore with today's needs. The welding of metallic foams is a subject that is still being studied and developed. In this study, studies in the literature are examined to understand the problems encountered in metallic foams during welding and to develop welding techniques. It is aimed to create a wide source for the welding of metallic foams by referring to the methods used and the advantages and disadvantages of the methods with this review. It has been determined that traditional welding methods have started to be replaced by advanced welding methods in the welding of metallic foams.

“…Therefore, it is needed to understand how these porous structures behave under these mechanical stresses to design materials that show adequate properties for the required application [2,3]. There are several metal foam studied [4][5][6][7][8][9][10] for their uniqueness features such as exceptional uniformity, light weight, high porosity, intrinsic strength, corrosion resistance and good electrical and thermal conductivity. However, most of the cases mechanical properties of respected metal oxides (MOs) of these metals were ignored.…”

Despite the importance of Nickel Oxide (NiO) in diverse functional applications, very little information is available on the mechanical properties of bulk or porous NiO or, mostly unnoticed. In this study, porous Ni-NiO foam was synthesized using space holding-powder metallurgy and sintering methods to produce opened-cell structure with macrogravel and Neolamarckia cadamba (Cadamba flower) like surface morphology. Four different types of porous Ni-NiO with different pore diameter of 35.65 ± 12.77, 36.10 ± 8.85, 68.20 ±7.36 and 62.45 ± 17.48 µm were fabricated for evaluating the effect of porosity on the mechanical properties of bulk porous Ni-NiO foam. The mechanical properties such as bulk crushing force of as synthesized Ni-NiO foam with various porosities such as 20.55, 27.35, 27.85 and 28.82 % exhibited the average crushing load of 115.40, 39.95, 138.10 and 151.20 N, respectively. This study suggests that crushing load of Ni-NiO foam is not only depending on the porosity but also on the sintering temperature and crystallite sizes of NiO. HIGHLIGHTS Ni-NiO foam is synthesized using space holding-powder metallurgy and sintering methods Different pore diameter is fabricated for evaluating the effect of porosity on the mechanical properties of bulk porous Ni-NiO foam Crushing strength of Ni-NiO foam is not only depending on the porosity but also on the sintering temperature and crystallite sizes of NiO GRAPHICAL ABSTRACT
