Abstract

In this study the Taguchi method is used to find the optimal process parameters for aluminium foammanufacturing. Porous metals are the unique materials used for light weight structural components, for filters andelectrodes and for shock or sound absorbing products. Recently, interesting foaming technology developments haveproposed metallic foams as a valid commercial chance. Metallic foam manufacturing techniques include solid statepowder methods, gas blowing processes, metal deposition onto a polymer precursor and liquid state processing.The aluminium foams presented in this study are produced by the powder metallurgy route starting fromaluminium powders with titanium hydride as the foaming agent. During the experimental work, many samples aremade by utilizing the combination of process parameters based on Taguchi orthogonal design. Three manufacturingparameters are studied: the silicon carbide content in powder mixture, the compaction pressure and the foamingtemperature. The Taguchi method is applied to design an orthogonal experimental array and a multi-objectiveoptimization approach is then proposed by simultaneously minimizing the relative density and maximizing theabsorbed energy. Verification test is also performed to prove the effectiveness of the presented technique.
