“…Besides these, Fe, [23][24][25][26][27][28] Zn, [29][30][31] and Ti [32][33][34] based variations have been produced and reported in the literature. [55][56][57] To decrease this drawback, MMSFs with cheaper filler material, namely expanded perlite [58][59][60][61][62][63][64][65][66][67][68] and pumice [69] were developed. [35] The filler material (or reinforcement in the composite technologist point of view) is usually built up from oxide ceramics or from iron based metals (steels).…”

Metal matrix syntactic foams (MMSFs, often referred as composite metal foams (CMFs)) are lightweight materials with high specific strength. MMSFs are on the borderline between metal matrix composites and metal foams. On one hand MMSFs are composites, because they are filled by hollow particles and the particles may add strength to the material. On the other hand, they are foams, because the hollow particles ensure porosity to the material. Among metallic foams, MMSFs exhibit outstanding specific mechanical properties due to the hollow inclusions that are typically made from ceramics or high strength alloys, therefore they can be applied as structural materials. The goal of this paper is to summarize the available data on the mechanical properties of MMSFs with aluminum matrix in order to give a strong support to the design engineers. Since the foams are most frequently loaded in compression, the main part of this paper is organized around the available standard related to the compressive properties of porous materials and metallic foams. The quasi-static results are complemented by properties measured at higher strain rates. Besides this, some insight into the basic fatigue properties as well as into the toughness of MMSFs is also provided.

“…Syntactic foams were produced by infiltration of the packed bed of particles with molten metal. Numerical investigations revealed good isotropy of the mechanical properties of the foams [46]. Unlike pumice, expanded perlite does not directly contribute into the quasi-static compressive response of syntactic foams due to poor mechanical strength.…”

“…On the one hand, tailoring parameters are considered to be those which are able to produce the larger fluctuations on MMSF mechanical properties. The most relevant of these parameters are sorted below: chemical composition of the metal matrix, heat treatment, porosity, hollow spheres properties [86,87], and aspect ratio H/D (height-to-diameter Metals 2020, 10, 149 5 of 19 ratio) of samples [62]. On the other hand, manufacturing parameters are those that highly govern the successful of synthesis of this kind of composite foams.…”

Metal matrix syntactic foams (MMSF) are foam composites obtained by filling hollow and/or porous particles into a metal matrix. MMSF are promising materials in defense, aerospace, automotive, marine and engineering applications. Mechanical and physical properties of MMSF can be tailored to reach better structural and/or functional behaviors by fitting processing and tailoring parameters. Some of these parameters are: reinforcement size, volume fraction, distribution of reinforcements and chemical composition. Three techniques are available to manufacture MMSF: Stir casting/vortex method (SC), powder metallurgy (P/M) and infiltration routes. Infiltration process is by far the main employed for making MMSF, it allows a large range of reinforcement (30 vol % to 78 vol %) and offers great advantages compared to other techniques. This paper reviews infiltration routes used to date, their advantages and drawbacks, the main processing parameters of each route, and a relation of representative studies developed to date on the synthesizing of MMSF by molten infiltration processes.
