Devices and methods for performing shear-assisted extrusion processes for forming extrusions of a desired composition from a feedstock material are provided. The processes can use a device having a scroll face having an inner diameter portion bounded by an outer diameter portion, and a member extending from the inner diameter portion beyond a surface of the outer diameter portion.

Extrusion feedstocks and extrusion processes are provided for forming extrusions of a desired composition from a feedstock. The processes can include providing a feedstock having at least two different materials and engaging the materials with one another within a feedstock container.

Methods for preparing metal sheets are provided that can include preparing a metal tube via shear assisted processing and extrusion; opening the metal tube to form a sheet having a first thickness; and rolling the sheet to a second thickness that is less than the first thickness.

The present invent on relates to a press for the direct extrusion of metallic material. The press comprises a supporting structure, a container receiving the metallic material to be extruded, a container holder element and a plurality of adjustment devices to adjust the position of the container holder with respect to the supporting structure. The container holder element is movable along an extrusion direction by means of a plurality of pads slidable along corresponding guides integral with the supporting structure. The press comprises at least one motorized member operationally connected to at least one of the adjustment devices to determine a variation of the position of the container holder with respect to the supporting structure.
