Abstract

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 welding (FSW) route. Pore structure of FG porous aluminum was observed nondestructively by X-ray CT inspection. The compression properties and deformation behavior of FG porous aluminum were obtained by the compression test. It was shown that the fabricated FG porous aluminum compressive test specimen had three different deformation stages and three plateau regions corresponding to the pore structures and types of aluminum alloy.
