Abstract

The precursor foaming process is one of the fabrication processes used for the fabrication of aluminum foam. In this study, the shaping of the aluminum foam was conducted by press forming during foaming precursor. A pin screen mold was proposed for the die of the press forming. It was shown that the pin screen mold could be used for the die of the press forming of the aluminum foam, and star-shaped aluminum foam can be obtained. From X-ray computed tomography (CT) observation, there is little effect of press forming by using pin screen mold on the pore structures of the obtained aluminum foam.
