Compression Properties of Al/Al–Si–Cu Alloy Functionally Graded Aluminum Foam Fabricated by Friction Stir Processing Route

Abstract

Functionally graded (FG) aluminum foam containing A1050 pure aluminum and ADC12 aluminum alloy was fabricated. The FG foam has the potential for its location of deformation to be controlled. Moreover, a FG foam with plateau regions and stresses corresponding to those of the uniform A1050 and ADC12 foams was obtained.
