Abstract
Metallic foams were synthesized by means of a self propagating high-temperature reaction producing a highly porous solid metal alloy with customizable material properties. Nano¬-scale aluminum (nAl) and nano-scale titanium (nTi) particles were mixed with either nano-scale aluminum passivated with a gasifying agent such as perfluoroalkyl carboxylic acid (C13F27COOH) or polytetrafluoroethylene (Teflon) (C2F4)n particles and pressed into pellets. These samples were then ignited with a laser producing a reaction product composed of an AlTi alloy that has a highly porous structure. Objectives of this study were to use combustion synthesis to create a functionally graded porous AlTi alloy and identify correlations between the product microstructure and parameters such as type and amount of gasifying agent present in the reactants. Photographic data allowed interpretation of the reaction propagation while characterization of the final product indicated porosity and morphology. Results fr
