Material strength improvements and reduction in processing costs are at the forefront of vehicle technologies development. For these reasons, a unique processing methodology has been explored that offers the potential for improved material properties and reduced power consumption. This method, Shear Assisted Processing and Extrusion (ShAPE), was performed on a variety of lightweight structural materials (Al and Mg-based). In this work, we will present findings that illustrate texture formation, second phase homogenization and mechanical properties that developed in response to high shear forces imparted during fabrication. Despite the elevated temperature processing (450°C) this solid state consolidation method has demonstrated an ability to refine grain the diameter in the final extrudate to less than 10µm in the material systems investigated. Results will showcase the ability to design and engineer novel materials that exhibit refined grain size and texture development through elevated temperature consolidation.
