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
