| Popis: | Aluminium alloy foams are manufactured by various methods, which include foaming of molten aluminum alloy by gas injection and powder metallurgical processing. Non-conventional methods such as direct energy deposition, syntactic method of metal foam fabrication have also been developed for the manufacturing of aluminium alloy foams. Aluminium alloy foams are cellular structure which consists of solid metal such as aluminium, steels and iron with micro pores filled with gases such as hydrogen, carbon di oxide, nitrogen, argon etc. In this research work in order to fabricate aluminum alloy 6063 foam, first aluminium alloy 6063 was melted by using stir casting method as it is economical and simple, 2 wt% titanium hydride was added and mixed into the molten aluminium alloy 6063 at temperature 800 ˚C and then the melt was allowed to cool down to room temperature in order to obtain aluminium alloy 6063 foam. The percent porosity and density of the fabricated aluminium alloy foam is determined with the help of Archimedes principle. |
