Devices and methods for performing shear-assisted extrusion, extrusion feedstocks, extrusion processes, and methods for preparing metal sheets
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.

Functionally graded coatings and claddings
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.

EXTRUSION SYSTEM AND METHOD OF SAME
An extrusion system includes a container defining a channel extending along an axis for holding a feedstock. A ram is located on a first axial side of the channel and a die assembly is located on a second axial side of the channel opposite the first axial side. The ram is axially movable to push the feedstock into the die assembly. The die assembly defines at least one aperture extending through a part of the die assembly. A shearing surface is configured to shear and heat the material prior to entering the at least one aperture. At least part of the shearing surface or the container are configured to rotate about the axis while the at least one aperture remains rotationally stationary.

Shape processes, feedstock materials, conductive materials and/or assemblies
Shear assisted extrusion processes (ShAPE) for forming Metal-NCCF extrusions are provided. The processes can include: using a die tool, applying a rotational shearing force and an axial extrusion force to a feedstock material comprising a metal and NCCF (NanoCrystalline Carbon Films); and extruding a mixture comprising the metal and NCCF through an opening in the die tool to form the Metal-NCCF extrusion. ShAPE feedstock materials are provided that can include a metal and NCCF. Conductive solid material mixtures are provided that can include a metal and a NCCF. Portions of the metals and NCCF of the material mixtures can have an isotropic crystallographic orientation. Assemblies relying in part on conductivity can include: a conductive solid material mixture that includes: a metal; and a NCCF.
