Abstract Scope |
To promote lightweighting of automotive structures, there is a need for new processing techniques that create a variation in properties within a single component. Customization would enable optimization of mechanical properties such as strength, ductility, and stiffness thereby reducing the need to specify a material or gage thickness for one region that is not needed in another. To this end, Shear Assisted Processing and Extrusion (ShAPE) was used to fabricate tubing having a gradient in alloy composition, and thus performance, along the length. Tubes that transition from 6061, to 7075, and back to 6061 have been extruded with an outer diameter of 12 mm and wall thickness of 1 mm. Morphology of the transition, microstructure, and mechanical properties are reported. The effect of process conditions are be discussed. Additionally, this work represents the first known thermomechanical processing technique whereby 7XXX has been joined without creating a weakened heat affected zone. |
