ABSTRACT:
A method for extruding metals and alloys, particularly difficult-to-work high temperature alloys, is described which comprises inserting a billet of the metal or alloy into an extrusion can, heating the canned billet to a temperature in a temperature range in which the ductility of the billet material is substantially maximum, cooling the canned billet sufficiently to establish a preselected temperature difference between the billet and can at which the difference between the flow stress of the billet material and the flow stress of the can material is substantially minimum, and extruding the canned billet to preselected shape.
