“…In this method, the appropriate melt viscosity is one of the key factors for obtaining foam products with homogeneous pore structures. In the past decade, many thickening agents, such as fly ash particles [4,5], Al 2 O 3 , SiC [6,7], Si 3 N 4 [6], MnO 2 [8], and Ca particles [9][10][11][12] have been used for aluminum foams. Among them, Ca is the most often used thickening agent in industrial production.…”

“…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.

“…The test was carried out under displacement control with a cross head speed of 1 mm s-1 according to standard test method for compressive properties of rigid cellular plastics (ASTM D 1621-00). Compressive strength was determined as the upper limit of the elastic region beyond which the cells undergo irreversible deformation or the first peak stress on the stress-strain curve [14]. Figure 1 shows cross sectional area images of the aluminum foam for measurement purposed.…”

This study concerns about the influence of foaming temperature which is applied to foaming process of aluminum foam to improve the stability of aluminum foam cell wall. Powder metallurgical method with four major foaming temperatures of 750°C, 800°C, 850°C and 900°C have been selected. Furthermore, the porosity of the foam was determined by ImageJ Analysis Software. Microhardness testing on the cell wall of aluminium foam was conducted according to ASTM E 92 using microhardness tester LM24AT with 200 grams and 15 s for loading time. The universal testing machine was applied to characterize the effect of foaming temperature on compression strength. The aluminum foam was observed in macroscopic and microscopic level using optical microscope (OM). The result revealed that the foaming temperature of 800°C gave the lowest value of porosity, with the highest hardness and compressive strength of 55.29 HV and 1.41 MPa, respectively. In addition, the highest porosity level was acquired by foaming temperature which was set at 900 °C. The lowest hardness value of 38.50 HV was obtained by foaming temperature of 700°C and the minimum compressive strength value of 0.75 MPa was exhibited when the foaming temperature was set at 900°C.
