Equal channel angular extrusion method
Abstract
According to one embodiment of the present invention, an equal channel angular extrusion (ECAE) method includes extruding a billet of material along a first axis in a first orientation through an ECAE die, extruding the billet along the first axis in a second orientation through the ECAE die, the second orientation oriented approximately 180° from the first direction, extruding the billet along the first axis in a third orientation through the ECAE die, the third orientation oriented approximately 90° from the second orientation, and extruding the billet along the first axis in a fourth orientation through the ECAE die, the fourth orientation oriented approximately 180° from the third orientation.
