“…However, the yield strength of 8.6MPa was observed for the aluminum foam ceramic composite which ceramic aggregates randomly distributed in its internal cell structure. This value of yield strength is very close to the values obtained by Xia et al [11] for aluminum foam composites produced from microsphere particles.…”

“…As observed from Table 1, the aluminum foam ceramic composite with a regular arrangement of ceramic tiles in its internal structure has a yield strength of 22MPa, which is higher than the values provided by Xia et al [11] and [12] and falls in the range given by Fraunhofer, IFAM [10]. However, the yield strength of 8.6MPa was observed for the aluminum foam ceramic composite which ceramic aggregates randomly distributed in its internal cell structure.…”

This research work investigates the mechanical properties of two distinct novel composites of aluminum foam made from the addition of recycled ballistic aggregates to the foams of aluminum alloy powder in regular and random patterns through powder metallurgy process. The mechanical attributes of these composites were examined in compression loading using digital image correlation (DIC) and compared to baseline properties of steel and aluminum foams obtained in the laboratory and literature respectively. The results obtained for aluminum foam ceramic composite made through the dispersion of ceramic aggregates in regular orientation showed an increase in its plateau stress, yield strength, strength/density ratio and relative density, but a decrease in its modulus of elasticity was observed. This observation was similar to the composite with a random arrangement of ceramic aggregates, except for a decrease noticed in its yield strength and elastic modulus.

Hybrid metal matrix syntactic foams (hybrid MMSFs) are particle reinforced composites in which the reinforcement is the combination of more than one grade of hollow spheres. The difference between the spheres can be in their chemical composition, dimension, physical properties etc. In this study AlSi12 matrix hybrid MMSFs with monomodal Globocer (Al2O3 and SiO2 based ceramic) and Globomet (pure Fe) reinforcements were produced by pressure infiltration. The investigation parameters were the ratio of the hollow sphere grades and the aspect ratio of the specimens. Microstructural investigations showed almost perfect infiltration and favourable interface layer, while quasi-static compression tests showed that the composition of the reinforcement and the aspect ratio of the specimens have determinative effect on the characteristic properties (compressive and flow strength, fracture strain, stiffness and absorbed energy). This nature of the MMSFs ensures the possibility to tailor their properties in order to optimise them for a given application.

“…In recent years, Al/Mg matrix syntactic foams are promising weight reduction materials, particularly attention for being used in automobile, aviation, and consumer products fields [4,5]. While, up to date, most of the investigations focused on aluminum or aluminum alloy matrices [6][7][8], only a few studies are available on Mg matrix syntactic foams, e.g., ZC63 magnesium-microballoon composite foams were fabricated by melt stir technique and the processing parameters on the distribution of fly ash microballoons were investigated.…”

Magnesium composite foams with 10 vol. % of hollow ceramic microspheres (CMs) were prepared by modified melt foaming method. Specimens with homogeneous pore structures were subjected to various heating temperature (150, 250, 320, 400, and 500 • C, respectively) and enduring times (1, 2, 4, 6, and 24 h, respectively). Evolution of microstructure and mechanical properties of the samples, before and after the heating processes were examined by applying X-ray diffraction technique (XRD), differential scanning calorimetry (DSC), scanning electron microscopy (SEM), and quasi-static uniaxial compression test. The results showed that as heating temperature and enduring time increasing, β-Mg 17 Al 12 phases gradually dissolved, resulting in a solid-solution strengthening effect. Meanwhile, internal stress relaxation in the matrix leads to the decrease of yield strength and micro hardness of the specimens. When compared with the unheated foams, the treated specimens possessed lower micro-hardness, yield strength, and energy absorption capacity due to the dissolution of β-Mg 17 Al 12 phases and the release of internal stress. However, higher strain hardening exponents for almost all of the treated composite foams were observed and the reasons were discussed. It is proposed that more factors should be taken into account when using heated composite foams in practical applications.
