Porous aluminum is a multifunctional material with lightweight and high energy absorption properties. In this study, A1050-ADC12-A6061 functionally graded (FG) porous aluminum of three layer structure was fabricated by friction stir processing (FSP) route. The compression properties and deformation behavior of FG porous aluminum was obtained by compression test. Moreover, pore structures of FG porous aluminum was observed by X ray CT inspection. It was shown that the fabricated FG porous aluminum had three different deformation stages and three plateau regions corresponding to the pore structure and types of aluminum alloy.
