Aluminum Foam Production Using Gas Injection In Melting, M.Sc. Thesis Sharif University of Technology ; Sadrnezhad, Khatiboleslam (Supervisor)
Abstract
In this research, aluminum composite foams reinforced with silicon carbides were manufactured using melt direct foaming with gas. The density of produced foams changed from 0.1 to 0.35 g cm-3. At first, simulation of bubble configuration was carried out in order to specify the effective parameters on foaming process. As the result, parameters such as ceramic particle volume percentage and gas type were selected. Results showed that, to process foam with acceptable stability, there was a critical minimum of ceramic particles concentration above which, stability of the foam was enhanced. Gas type was also showed to have a significant effect on foam stability. Argon, carbon dioxide and air were...
