Abstract

It is difficult to bond metal foams by welding process. The solid state diffusion bonding process is examined using closed-cell aluminum foam (ALPORAS). Utilizing the superplastic deformation of inserted 5083 aluminum alloy, the oxidation film is fractured. The bonding strength was evaluated through 4 points bending tests.
