摘要： 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.

摘要： A shear assisted extrusion process for producing cladded materials wherein a cladding material and a material to be cladded are placed in sequence with the cladded material positioned to contact a rotating scroll face first and the material to be cladded second. The two materials are fed through a shear assisted extrusion device at a preselected feed rate and impacted by a rotating scroll face to generate a cladded extrusion product. This process allows for increased through wall strength and decreases the brittleness in formed structures as compared to the prior art.

摘要： 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.

摘要： In some preferred embodiments, an extrusion die for metallic material capable of obtaining a high quality extruded article can be provide while securing sufficient strength and durability. The extrusion die is provided with a die holding case 20 having a dome portion 21 with an external surface functioning as a metallic material pressure receiving surface 22, the metallic material pressure receiving surface 22 being disposed so as to face rearward, a male die 30 held in the die holding case 21, and a female die 40 held in a front portion of the die holding case 20. The metallic material pressure receiving surface 22 is formed into a convex configuration, and a porthole 24 is formed in the dome portion 21. The central axis A2 of the porthole 24 is inclined to the central axis A1 of the die holding case 20. The metallic material pressed against the metallic material pressure receiving surface 22 is introduced into the die holding case 20 through the porthole 24 and passes through the extrusion hole 11.
