Porous aluminum has received much attention in various industrial fields due to their high energy absorptivity together with their superior lightweight. In this study, using aluminum alloy die casting ADC12, the porous aluminum changing the pore structures in one individual was tried to fabricate by FSP (Friction Stir Processing) route precursor method. At first, the effects of the contained gases and the amount of added blowing agent on the porosities and pore structures of ADC12 porous aluminum with uniform pore structure were examined. On the basis of the results, the fabrication possibilities of two types of ADC12 porous aluminums changing the pore structures were discussed. One of the porous aluminums has two different porosities and average diameters of pores and the other has two different porosities with almost same average diameter of pores. It was shown that the two types of ADC12 porous aluminums with graded porosities and pore structures were practically fabricated by using the FSP route precursor method, through the observations of pore structures by X-ray computed tomography of the fabricated porous aluminums.
