Widespread application of high strength Al sheets is limited primarily due to their poor room temperature formability. Selective microstructural modification can enable formability improvements locally while retaining strength in other areas. Friction stir processing (FSP)method have shown promising results towards this goal. In this poster we will present current progress in local formability improvements using high speed friction stir processing in age hardened automotive Al sheets. Local formability improvements as high as 30% has been shown in 7085-T76 as measured by minimum bend radii (r/t) ratios established with V-bending tests. Comparable results in 7055-T6 alloys will also be presented.
