Melt foaming method is one of cost-effective methods to make metal foam and it has been successfully applied to fabricate Mg foams. In this research, AZ31 Mg alloy ingot was used as a metal matrix, using AlCa granular as thickening agent and CaCO 3 powder as foaming agent, AZ31 Mg alloy foams were fabricated by melt-foaming method at different foaming temperatures. The porosity was above 41.2%~73.3%, pore size was between 0.38~1.52 mm, and homogenous pore structures were obtained. Microstructure and mechanical properties of the AZ31 Mg alloy foams were investigated by optical microscopy, SEM and UTM. The results showed that pore structure and pore distribution were much better than those fabricated at lower temperatures. The compression behavior of the AZ31 Mg alloy foam behaved as typical porous materials. As the foaming temperature increased from 660

“…Generally, the mechanical properties of metallic foams depend on the property of cell wall material [4][5][6][7], the relative density [1][2][3], and the cell structure [8,9]. For Al 2 O 3 short fibers reinforced Zn-22Al composite foams, the microstructure may play an important role on the compressive properties of the composite foams.…”

“…However, the studies on the correlation between microstructure and compressive properties of metallic foams are scarce. Some investigations exhibited that the secondary phase or component such as viscosity increasing agent, the brittle phase and eutectic phase in cell wall material is an important factor affecting the mechanical response of the foams [9][10][11][12][13][14]. Markaki and Clyne [13] examined the mechanical properties of three closed-cell foams with similar relative densities and cell structures but evident differences in cell wall microstructure and found that cell wall ductility and toughness were impaired by high volume fractions of coarse eutectic, fine oxide films, and large brittle particles.…”

Moreover, Yu and coworkers [9] found that the presence of SiC p particles in ZA22-SiC p composite foams resulted in large stress fluctuation during compression, and this led to a slightly high energy absorption capacity and a low energy absorption efficiencies as compared with ZA22 foams.…”

This investigation aims to assess the mechanical behavior and energy absorption properties of the light sandwich panels made of open‐cell polymer and nickel/polymer foam. A portion of the ultralightweight foam sandwich panels (14.23 g) is produced by 3D printing and electrodeposition methods with 35, 45, and 55 seeds numbers, which lead to 4, 5, and 6 pores per inch (PPI); then a uniaxial compression test is applied to measure maximum compressive strength, strength‐to‐weight ratio, energy absorption density, efficiency, and complementary energy. The results indicate that compared with typical open‐cell nickel foams and polymer precursors when the thickness of the nickel layer is about 50 micrometers, the aforementioned properties of the sandwich panel shows a significant improvement. Improvement of properties changes by increasing PPI and CAD seed numbers. In a nickel/polymer sandwich panel with 6 PPI, the first maximum compressive strength, specific energy absorption, and energy absorption efficiency reach 0.93 (MPa), 0.93 (J.boldg−1), and 60%, respectively. 3D‐RP‐Ni‐6 improves 3D‐RP‐6 first maximum compressive strength and specific energy absorption by six times and two times, respectively. These significant improvements in the properties of these sandwich panels make these advanced materials a suitable candidate for the high strength applications.
