Abstract

Porous aluminum is expected to be a multifunctional material of automobile which can realize improvement of both collision safety and fuel efficiency, because of its high energy absorption ability with lightweight property. In this study, closed-cell porous aluminum was fabricated by friction stir processing (FSP) route using inexpensive aluminum plates. This proposed FSP route has great potential to realize high productivity, low energy consumption and low-cost manufacturing. The aim of this study is to investigate the validity of the FSP route for fabricating the closed-cell porous aluminum. Also, the effect of the alumina addition for the purpose of pore stabilization to the morphology of the pores and porosity was investigated. It was shown that porous aluminum with the porosity of 80-90% was realized by adding alumina and optimizing the temperature condition.
