Comparison of Friction Extrusion Processing From Bulk and Chips of Aluminum-Copper Alloys

Friction extrusion processing describes the of metallic materials via severe plastic deformation imposed by friction-induced heat and shear strain. The process features relative rotational movement between die feedstock material, resulting in complex introduction affecting local thermal material flow conditions. While powders, chips bulk for improvement extrudate properties has been studied independently, this work focuses on direct comparison friction AlCu10 under identical Analysis machine response microstructure extruded wires allows first conclusions, identifying characteristics requirements from different materials.
