“…Nevertheless, it was also noticed from the calculations that there was no strong interaction between the aging heat treatment and plateau-end-point values. When these findings are compared with the outcomes published in previous investigations 15,21,22,24 focusing on only pumice and only expanded glass-filled aluminum syntactics, it can be asserted that compressive strength values of fabricated hybrid foams are higher. However, for plateau strength and energy absorption values, it is difficult to say the existence of any increasing or decreasing trend.…”

“…In another work, Bolat et al 21 produced 2-4 mm pumice-added AA7075 foams and the density levels exceeded 1.60 g/cm 3 . As for expanded glass, Bolat et al 15 applied the same technique offered in this paper and proclaimed that density intervals altered between 1.22-1.30 g/cm 3 and 1.41-1.50 g/cm 3 for 2-4 mm and 1-2 mm glass-filled samples, respectively. In addition, through the counter-gravity infiltration casting technique, Fiedler et al 24 dropped the density level to 1-1.1 g/cm 3 for expanded glass-reinforced A356 matrix.…”

“…It was deduced from Table 1 that there was an adverse relationship between the reinforcement diameter and total foam density results. This is a predictable outcome if the findings put forward in the previous researches used the same technique are considered, 15 and stems from the high packing order behavior of the small-sized reinforcements that triggers particle breakage during the application of the process pressure. If the previous papers are scrutinized, Taherishargh et al 22 found that 2.8-4 mm pumice-filled foams had a density range of 1.48-1.50 g/cm 3 .…”

“…[12][13][14] In recent years, because of the fact that thin-walled spheres are considerably expensive, cellular/porous alternatives such as expanded perlite, expanded glass, and expanded clay have been preferred by diversified research teams owing to their low cost. [15][16][17] Up to date, to figure out the deformation style of MMSFs, the majority of the analytical, experimental, and numerical endeavors have focused on the effects of different filler/matrix combinations, matrix type, reinforcement size, and bimodality on the physical and mechanical properties. However, there are a few works by Su et al 18 and Májlinger et al 19 analyzing the impact of the reinforcement hybridization on the mechanical behaviors of the MMSFs.…”

Over the past years, the number of scientific efforts on aluminum matrix syntactic foams (AMSFs) has increased in a noteworthy manner, and different investigation teams have tried to figure out the physical, microstructural, and mechanical properties of AMSFs. In this paper, different from the previous valuable efforts, an industrial-focused cold chamber die casting machine was utilized during the fabrication instead of commonly used lab-scale techniques. Also, the effects of the reinforcement diameter on the compressive features were analyzed for pumice and expanded glass-added hybrid AMSFs. To ascertain the mechanical properties, quasi-static compression tests were conducted and stress–strain curves were obtained. During the compression tests, the deformation styles of the hybrid foams were followed to comprehend their damage mechanisms. Moreover, half of the samples were subjected to artificial aging treatment and the results were checked up with as-cast samples. According to experimental outcomes, it was obvious that the artificial aging treatment caused superior mechanical properties and triggered brittle-style deformation.

For composite metal foam structures to be used as load‐bearing and energy‐absorbing elements, comprehensive testing should be done. Therefore, an extensive characterization of foam‐filled structures by various load types, such as axial and lateral compression, as well as three‐point bending, is carried out, aiming to differentiate the behavior of various cross‐sectional geometry foam‐filled hollow sections and the application of a tough epoxy adhesive and a ductile polysiloxane adhesive. Applying the epoxy adhesive improves the overall energy absorption by 10 % during axial compression compared to the sum of the foam and empty hollow section. The application of the polysiloxane adhesive over the epoxy one increases the deflection at failure during three‐point bending by an average of 58 %. The deformation and strength during axial compression and three‐point bending are hollow section dominated, while the foam core dominates the deformation and the strength during lateral compression for both produced composite foam‐filled hollow sections with epoxy and polysiloxane adhesive bonding.This article is protected by copyright.

On the way to the real industrial applications of the metal matrix composite foams, the machining issue is highly critical in terms of dimensional accuracy, surface quality, and design diversity. Therefore, especially for lightweight automotive and aerospace components, the drilling machinability properties of cellular glass‐added aluminum composite foams were examined in this paper, and this is the first initiative in the literature specific to millimeter‐scale glass and aluminum‐zinc matrix combination. To comprehend the drilling properties, the outputs of thrust force, cylindricity, material removal rate, specific cutting coefficient, circularity error, damage factor, surface roughness, and chip formation were measured elaboratively. The results showed that cylindricity and damage factor of foams elevated with the increased feed rates (from 0.05 mm×rev−1 to 0.2 mm×rev−1) and cutting speeds (from 25 m×min−1 to 100 m×min−1). Maximum thrust force value reached up to 150 N for 0.2 mm×rev−1 feed and 25 m×min−1 cutting speed. Besides, specific cutting coefficient values ranged between 360 MPa and 114 MPa. The highest surface roughness of 58.3 μm was obtained with the lowest cutting speed of 25 m×min−1, and the long/continuous chip structure converted into a separate/short structure based on rising feed and cutting speeds.
