“…Figure 8 shows the plateau stress of Al-3.7 pct Si-0.18 pct Mg foam as a function of relative density, along with those of strengthened Al alloy foams reported in previous studies. [6,13,[16][17][18] The plateau stress of Al-3.7 pct Si-0.18 pct Mg foam is comparable to that of strengthened Al-6 vol pct TiB 2 , [13] Al-9 pct Si-1 pct Mg-5 to 15 vol pct SiC, [16] and Al-7 to 12 pct Si foams [18] with similar relative density. Namely, the plateau stress of Al-3.7 pct Si-0.18 pct Mg foam is successfully enhanced as in the case of the other strengthened foams.…”

YEONG HWAN SONG, MASAKAZU TANE, TAKUYA IDE, YOSHIHIRO SEIMIYA, BO YOUNG HUR, and HIDEO NAKAJIMA Al-3.7 pct Si-0.18 pct Mg foams strengthened by AlN particle dispersion were prepared by a melt foaming method, and the effect of foaming temperature on the foaming behavior was investigated. Al-3.7 pct Si-0.18 pct Mg alloy containing AlN particles was prepared by noncompressive infiltration of Al powder compacts with molten Al alloy in nitrogen atmosphere, and it was foamed at different foaming temperatures ranging from 1023 to 1173 K. The porosity of prepared foam decreases and the pore structure becomes homogeneous with increasing foaming temperature. When the foaming temperature is higher than 1123 K, homogeneous pores are formed in the prepared ingot without using oxide particles and metallic calcium granules, which are usually used for stabilizing a foaming process. This stabilization of the foaming at high temperatures is possibly caused by Al 3 Ti intermetallic compounds formed at high temperature and AlN particles. Compression tests for the prepared foams revealed that the absorbed energy per unit mass of prepared Al-3.7 pct Si-0.18 pct Mg foam is higher than those of aluminum foams strengthened by alloying or dispersion of reinforcements. It is remarkable that the oscillation in stress, which usually appears in strengthened aluminum foams, does not appear in the plateau stress region of the present Al-3.7 pct Si-0.18 pct Mg foam. The homogeneity in cell walls and pore morphology due to the stabilization of pore formation and growth by AlN and Al 3 Ti particles is a possible cause of this smooth plateau stress region.

Carbon nanotube (CNT) reinforced Al composite foams with different CNT contents are fabricated through an improved powder metallurgy approach by combining in situ chemical vapor deposition (CVD), short time ball-milling, and space-holder method. The CNTs are uniformly dispersed on the surface of Al particles by in situ CVD process, followed by a short time ball-milling process enabling an excellent interfacial bonding between CNTs and the Al matrix. The pore size and microstructures of the composite foams can be well tailored by the carbamide particle templates. The yield strength and energy absorption capacity of composite foams reach 18.1 MPa and 15.8 MJ m À3 with 3.0 wt% CNT addition, which are %1.3 and %3.6 times higher than those of pure Al foam, respectively. The energy absorption efficiency of the CNT/Al composite foams achieves a maximum of %0.86, when the CNT content is up to 3.0 wt%. Additionally, compressive and energy absorption properties of the CNT/Al composite foams increase with the increment of relative density. The failure mode of the Al foam changes from plastic mode to brittle mode combined with ductile mode, as a result of CNT addition.
