Systems and methods for production of metallurgically bonded clad billet and products thereof, and metallurgically bonded clad billet
A method of producing a clad billet includes inserting a solid carbon or low-alloy steel (CS) material into a hollow interior of the slightly larger diameter (CRA) cylinder so that a standoff gap is provided between an outer surface of the (CS) material and the inner diameter of the (CRA) cylinder; providing an explosive material around the (CRA) cylinder; detonating the explosive material to collapse at least the inner diameter of the corrosion resistant alloy cylinder onto the outer surface of the solid carbon or low-alloy steel material and eliminate the standoff gap, creating at least a partial metallurgical bond at an interface with the outer surface and resulting in a composite billet assembly; and extruding the composite billet assembly to reduce its size and form the clad billet having a metallurgical bond between the (CS) material and the (CRA) cylinder.

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.

STEEL-VANADIUM ALLOY CLADDING FOR FUEL ELEMENT
This disclosure describes various configurations and components for bimetallic and trimetallic claddings for use as a wall element separating nuclear material from an external environment. The cladding materials are suitable for use as cladding for nuclear fuel elements, particularly for fuel elements that will be exposed to sodium or other coolants or environments with a propensity to react with the nuclear fuel.
METHOD OF METAL FOAM EXTRUSION AND ARTICLES MANUFACTURED THEREFROM
A method for manufacturing a foam in a conduit comprises extruding a metal conduit. A metal foam powder is injected into a cavity of the metal conduit. The metal foam powder is activated to form a metal foam in the cavity of the metal conduit. A device for producing a foamed metal comprises an extruder that comprises one or more screws for extruding a metal through a die to form a conduit. The die comprises a plurality of ports for injecting a metal foam powder into a central hollow cavity or a wall cavity of the conduit. The device comprises a pressurizing section for increasing pressure on the metal foam powder and a thermal section for increasing the temperature of the metal foam powder to facilitate its expansion into a metal foam.
