    摘要： The present disclosure provides methods for preparing an extruded product from a solid billet. The methods can include providing an as-cast billet for extrusion; applying a simultaneous rotational shear and axial extrusion force to the as-cast billet to plasticize the as-cast billet; and extruding the plasticized as-cast billet with an extrusion die to form an extruded product. Methods for preparing extruded products from billets can also include: providing a billet for extrusion; while maintaining a majority of the billet below 100° C., applying a simultaneous rotational shear and axial extrusion force to one end of the billet to plasticize the one end of the billet; and extruding the plasticized one end of the billet with an extrusion die to form an extruded product. Methods for preparing an extruded product from a billet can also include providing a billet for extrusion; applying a simultaneous rotational shear and axial extrusion force to the billet to plasticize the billet; extruding the plasticized billet with an extrusion die to form an extruded product; and artificially aging the extruded product for less than the ASTM recommended amount of time.

    摘要： Riveted assemblies are provided that can include a substrate extending between two ends to define opposing substrate surfaces having a first opening extending between the opposing substrate surfaces; a metal-comprising substrate extending between two ends to define opposing metal-comprising substrate surfaces having a second opening extending between the opposing metal-comprising substrate surfaces. The riveted assemblies can further provide that the first and second openings complement one another when the substrate and metal-comprising substrate are engaged; and a rivet shaft extends through the openings and engages the substrate with the rivet head and the metal-comprising substrate with the rivet stop head, at least a portion of the stop head being mixed with, and forming a metallurgical bond with the metal-comprising substrate. Assemblies are provided that can include a rivet stop head mixed with, and metallurgically bonded with a metal-comprising substrate.
    Methods for affixing substrates to one another are also provided. The methods can include providing a substrate defining an opening configured to receive a rivet shaft; providing a metal-comprising substrate defining a complimentary opening; operatively engaging the substrates with the rivet shaft; and forming a stop head from the rivet shaft to affix the substrates. The method further includes that the stop head mixes with, and forms a metallurgical bond with the metal-comprising substrate. Methods for mixing materials to form a metallurgical bond are also provided. The methods can include forming a metallurgical bond between a stop head of a rivet and a metal-comprising substrate.

    摘要： Shear assisted extrusion apparatus, tools, inserts, and/or methods are provided. The apparatuses can include: an extrusion receiving channel operably engaged with a tool to receive extruded material; and one or more openings aligned between the spindle ends, the openings configured to convey fluid to the extruded product. Example tools can include one or more openings aligned between the tool ends. Example methods can include quenching plasticized feed material before exiting the spindle. A spindle assembly and/or tool assembly inserts are also provided that can include a sleeve extending within one or both of the spindle assembly or tool assembly of the apparatus; and openings within the sleeve configured to convey fluid to within one or both of the receiving channel of the spindle assembly or the tool assembly.

    摘要： A method for preparing a shear-assisted extruded material from a powder billet is provided, the method comprising providing a billet of material in substantially powder form; applying both axial and rotational pressure to the material to deform at least some of the contacted material; and extruding the material to form an extruded material. A method for preparing shear-assisted extruded material is provided, the method comprising applying both axial and rotational pressure to stock material to form an extruded material at a rate between 2 and 13 m/min. A method for preparing shear-assisted extruded material is provided. The method comprises applying both axial and rotational pressure to stock material to form an extruded material; and aging the extruded material for less than 3 hours. A method for preparing shear-assisted extruded material is provided. The method comprises providing a stock material for shear-assisted extrusion; and applying both axial and rotational force to the stock material to form an extruded material, wherein the axial force does not decrease during the extrusion.
