Patent number: 11684959Abstract: 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.Type: GrantFiled: February 4, 2022Date of Patent: June 27, 2023Assignee: Battelle Memorial InstituteInventors: Scott A. Whalen, Vineet V. Joshi, Md. Reza-E-Rabby, Jens T. Darsell, Mageshwari Komarasamy, Curt A. Lavender, Glenn J. Grant, Aashish Rohatgi, William E. Frazier, III

Publication number: 20230088412Abstract: 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.Type: ApplicationFiled: November 9, 2022Publication date: March 23, 2023Applicant: Battelle Memorial InstituteInventors: Vineet V. Joshi, Glenn J. Grant, Curt A. Lavender, Scott A. Whalen, Saumyadeep Jana, David Catalini, Jens T. Darsell

Publication number: 20230081786Abstract: A process for forming extruded products using a device having a scroll face configured to apply a rotational shearing force and an axial extrusion force to the same preselected location on material wherein a combination of the rotational shearing force and the axial extrusion force upon the same location cause a portion of the material to plasticize, flow and recombine in desired configurations. This process provides for a significant number of advantages and industrial applications, including but not limited to extruding tubes used for vehicle components with 50 to 100 percent greater ductility and energy absorption over conventional extrusion technologies, while dramatically reducing manufacturing costs.Type: ApplicationFiled: November 11, 2022Publication date: March 16, 2023Applicant: Battelle Memorial InstituteInventors: Vineet V.

Publication number: 20180037975Abstract: Nanocrystalline metal powders comprising tungsten, molybdenum, rhenium or niobium can be synthesized using a combustion reaction. Methods for synthesizing the nanocrystalline metal powders are characterized by forming a combustion synthesis solution by dissolving in water an oxidizer, a fuel, and a base-soluble, ammonium precursor of tungsten, molybdenum, rhenium, or niobium in amounts that yield a soichiometric burn when combusted. The combustion synthesis solution is then heated to a temperature sufficient to substantially remove water and to initiate a self-sustaining combustion reaction. The resulting powder can be subsequently reduced to metal form by heating in a reducing gas environment.Type: ApplicationFiled: October 17, 2017Publication date: February 8, 2018Inventors: John G.
