| Popis: | Aluminum foams are having versatile applications in light weight structures, sandwich cores, mechanical damping, energy absorbers and acoustic absorption in automobiles, aerospace industries and defense sector. In the present study, two aluminum foams were synthesized by liquid metallurgy by adding different viscosity enhancing agents, one by adding 5 wt% Calcium metal granules (named as Ca-foam) and another by 5 wt% Boron carbide particles (named as B4C-foam). Both foams were manufactured by adding Calcium carbonate as a foaming agent. The foams were characterized for microstructure, cell morphology, phases formed and relative density. Relative density was calculated as 0.22 and 0.34 for Ca-foam and B4C-foam respectively. Quasi-static compression tests were performed on universal testing machine. Stress–strain graph showed higher average plateau stress for B4C-foam than Ca-foam confirming the brittle fracture for both foams. |
