Porous aluminum is a lightweight material with high energy absorption properties. In this study, impact test of A1050-ADC12 functionally graded porous aluminum fabricated by friction stir processing (FSP) route was carried out. It was shown that deformation began from low strength A1050 layer and thereafter high strength ADC12 layer deformed. This result is consistent with the result of static compression test of A1050-ADC12 functionally graded porous aluminum. Consequently, it was shown that A1050-ADC12 functionally graded porous aluminum has the potential for its location of deformation to be controlled.
