Abstract

The purpose this study is to reduce the cost of porous aluminum (Al) by using calcium carbonate (CaCO₃) as a foaming agent. First, fabricated A6061 precursor with CaCO₃ and Alumina (Al₂O₃) addition by friction stir processing. Next, precursor was heating and foaming in electric furnace. Pore structures of obtained porous Al were nondestructively observed by X-ray CT. As the result, this specimen by using CaCO₃ as a foaming agent was successfully fabricated.
