Joining of two foamed porous aluminum by roll forming immediately after foaming

In this study, the joining of porous aluminum by roll forming was attempted. Two precursors were foamed heat treatment, and softened immediately after foaming roll-formed. It shown that simultaneously formed joined while maintaining structure aluminum. results four-point bending test samples, pores observed at fracture surfaces, indicating strong can be achieved forming. addition, it found optimizing width guide rails during forming, in accordance with size precursors.
