Abstract

Closed-cell porous aluminum was fabricated using gases intrinsically contained in aluminum alloy die castings without using a blowing agent. By incorporating the friction stir processing technique, porous aluminum with a porosity of more than 50 pct was successfully obtained at a holding temperature of 923 to 948 K and a holding time of 10 minutes. This proposed die-casting route has high potential for fabricating porous aluminum at a low cost by a higher productivity process.
