Abstract
The present disclosure provides methods for preparing an extruded product from a solid billet. The methods can include providing an as-cast billet for extrusion; applying a simultaneous rotational shear and axial extrusion force to the as-cast billet to plasticize the as-cast billet; and extruding the plasticized as-cast billet with an extrusion die to form an extruded product. Methods for preparing extruded products from billets can also include: providing a billet for extrusion; while maintaining a majority of the billet below 100° C., applying a simultaneous rotational shear and axial extrusion force to one end of the billet to plasticize the one end of the billet; and extruding the plasticized one end of the billet with an extrusion die to form an extruded product. Methods for preparing an extruded product from a billet can also include providing a billet for extrusion; applying a simultaneous rotational shear and axial extrusion force to the billet to plasticize the billet; extruding the plasticized billet with an extrusion die to form an extruded product; and artificially aging the extruded product for less than the ASTM recommended amount of time.
