Abstract Scope Industrial scale nanostructuring via High Shear Deformation (HSD) can alter the properties of metals and alloys to increase their performance and extend their lifetimes. These factors in combination facilitate the use of lightweight alloys for transportation applications. We will examine how nanostructuring aluminum alloys can improve the fuel economy of vehicles by reducing the weight of electrical wires. Applying HSD non-isothermally alters precipitation; increasing electrical conductivity of Al-Mg-Si alloys to over 57%IACS while also increasing strength by 55%. Careful microstructural analysis of Al alloys before and after HSD process was performed to show how HSD changes grain size, dislocation density and precipitate size distribution. In addition, means to implement HSD at economically feasible production rates will be addressed.
