Aluminum foam is a multifunctional material with a light weight and a high energy absorption. In this study, an A1050 (pure Al)-A6061(A1-Mg-Si)-ADC12(A1- Si-Cu) aluminum alloy three-layered-structure functionally graded (FG) aluminum foam was fabricated by the friction stir welding (FSW) route. The pore structures and elemental Cu content of the fabricated A1050-A6061-ADC12 FG aluminum foam were observed nondestructively by X-ray CT inspection and Electron Probe Microanalysis (EPMA), respectively. It was shown that three-layered A1050-A6061-ADC12 FG aluminum foam can be fabricated with different pore structures and elemental Cu contents in each layer. The compression properties and deformation behavior of the A1050-A6061-ADC12 FG aluminum foam were obtained by a compression test. It was shown that the fabricated A1050-A6061-ADC12 FG aluminum foam exhibited three different deformation stages and three plateau regions corresponding to the pore structures and types of aluminum alloy in each layer. © 2013 The Japan Institute of Metals and Materials.
