Abstract

A method for shear-assisted extrusion of a billet or feedstock can involve extruding a first portion of the feedstock through a die opening while rotating the die face relative to the feedstock at a first rotational rate and applying a first axial extrusion force. A second portion of the feedstock can be extruded through the opening while rotating the die face at a second rotational rate and applying a second axial extrusion force. This can establish different temperature ranges at the interface for each portion, resulting in a first extruded portion with different physical properties than the second extruded portion.
