“…[10] The intrinsic hydrogen content of AlMg50 powder is sufficient to achieve a moderate expansion both in Al-and Zn-based alloys, see Figure 1. In powder compact method, volume expansions of 350-650% for Al and Al-based alloys [21][22][23][24][25][26][27] and 600-1000% for Zn and Zn-based alloys [21,26,28,29] have been reported in the literature.…”

Al and Zn Foams Blown by an Intrinsic Gas Source

et al. 2010

A method was developed to produce Al‐ and Zn‐based foams with a uniform distribution of small cells. Pre‐alloyed AlMg50 powder containing hydrogen was used as a replacement for the usual blowing agent TiH2. AlMg50 powder released gas uniformly in the entire sample, caused the nucleation of a large number of cells and led to simultaneous growth that finally resulted in a uniform cell structure. The expansion behavior of these foams was studied by means of in situ X‐ray radioscopy. The macrostructure of the solidified foams was then analyzed through optical microscopy and X‐ray tomography and proved to be very uniform. The high strength of the foams was demonstrated by uni‐axial compression tests.

“…For instance, the peak strength of Al alloy foams with similar density is usually 15-20 MPa. [21,23,34,35] The high strength of AlMg15Cu10 foams can be attributed to two factors. Firstly, the uniform cell size distribution, the lower average cell size and low number of defects.…”

“…Some of them [10,11] are about mechanical, thermal, electrical properties of the product. During the last decade, most research [11,12] focused on compressive strength test. The mismatch between the decomposition temperature of the TiH 2 and the melting point of the pure metal or its alloy is the biggest problem in the PM process.…”

Novel Molding Method and Enhanced Cell Homogeneity in the Powder Metallurgical Route for Production of Closed Cell Al-Foam

et al. 2017

TiH2 content, mixing, pressing, different mold filling rate as the factors which affect foaming process on the powder metallurgical route were investigated. TiH2 was added in the amount of 0.5-1-1.5-2 wt% to adjust the proper amount. Differential scanning calorimetry tests were conducted on the TiH2 powders in order to obtain optimum hydrogen releasing condition. Aluminum and TiH2 powders were blended with the different speedtime combination. The mix was compacted at different pressures with the aim of explaining of the oxide layer deformation. An acceptance-rejection criterion was developed and used in pore analysis. Also, the using of a borosilicate glass molding technique are completely original and a new approach.

“…Various production techniques with different chemical compositions greatly affect the microstructural and mechanical properties of foams. A great number of studies [3][4][5][6][7][8][9][10] are available in the literature which contains conventional tests applied to the Al foams to reveal their mechanical performances under different loading conditions. Particularly, the quasistatic compressive responses of Al foams were investigated by a number of researchers and it was found that the stress-strain graphs of foams show a significant characteristic with three distinct regions.…”

This article considers the sandwich structures with aluminium (Al) foams of various thicknesses in conjunction with skins composed of fibre-metal laminates (FML). The FMLs with Al sheet and glass fiber reinforced polypropylene (GFPP) composites were integrated with Al foam for composing the sandwich panels. The FML-foam sandwich systems were manufactured by hot pressing in a mold at 200 C under 1.5 MPa pressure. The bonding between the components of the sandwich was achieved by various surface modification techniques, i.e., silane surface treatment, PP adhesive film additition, and their combination. The Al sheet/Al foam sandwiches were also prepared by bonding the components with an epoxy adhesive for comparing the effect of GFPP on the mechanical performance of the sandwich structures. The energy absorption capacities together with compressive mechanical behavior of both Al foams and FML-foam sandwich systems were evaluated by flatwise compression tests. Experiments were performed on samples of varying foam thicknesses.
