Abstract
A method for preparing a shear-assisted extruded material from a powder billet is provided, the method comprising providing a billet of material in substantially powder form; applying both axial and rotational pressure to the material to deform at least some of the contacted material; and extruding the material to form an extruded material. A method for preparing shear-assisted extruded material is provided, the method comprising applying both axial and rotational pressure to stock material to form an extruded material at a rate between 2 and 13 m/min. A method for preparing shear-assisted extruded material is provided. The method comprises applying both axial and rotational pressure to stock material to form an extruded material; and aging the extruded material for less than 3 hours. A method for preparing shear-assisted extruded material is provided. The method comprises providing a stock material for shear-assisted extrusion; and applying both axial and rotational force to the stock material to form an extruded material, wherein the axial force does not decrease during the extrusion.
