Title

Ultrafine Grained Aluminum Alloys via Friction Stir Processing

Abstract

Friction stir processing (FSP) is a new technique for refining grain size in metallic materials. In this paper, a brief overview of the state-of-the-art of FSP for obtaining ultrafine grained (UFG) microstructure in aluminum alloys is presented. The current results indicate that bulk UFG aluminum alloys can be obtained via FSP. Cast material can be converted to UFG material in a single pass. An attractive feature of this process is the ability to refine microstructure in commercially available high strength aluminum alloys.
