  • Additive manufacturing methods using aluminum-rare earth alloys and products made using such methods
    Patent number: 11491546
    Abstract: Described herein are additive manufacturing methods and products made using such methods. The alloy compositions described herein are specifically selected for the additive manufacturing methods and provide products that exhibit superior mechanical properties as compared to their cast counterparts. Using the compositions and methods described herein, products that do not exhibit substantial coarsening, such as at elevated temperatures, can be obtained. The products further exhibit uniform microstructures along the print axis, thus contributing to improved strength and performance. Additives also can be used in the alloys described herein.
    Type: Grant
    Filed: July 9, 2020
    Date of Patent: November 8, 2022
    Assignees: UT-Battelle, LLC, University of Tennessee Research Foundation, Iowa State University Research Foundation, Inc., Eck Industries Incorporated
    Inventors: Alex J. Plotkowski, Orlando Rios, Sudarsanam Suresh Babu, Ryan R. Dehoff, Ryan Ott, Zachary C. Sims, Niyanth Sridharan, David Weiss, Hunter B. Henderson

  • Surface-hardened aluminum-rare earth alloys and methods of making the same
    Patent number: 10584403
    Abstract: Embodiments of surface-hardened aluminum-rare earth alloys and methods of making the alloys are disclosed. In some embodiments, the alloy comprises aluminum and 4 wt % to 60 wt % of a rare earth component X having a maximum solid solubility of ?0.5 wt % in aluminum. The surface-hardened alloy component has an alloy bulk portion and a hardened alloy surface portion. At least a portion of the hardened alloy surface portion has a Vickers hardness that is at least 30% greater than a Vickers hardness of the alloy bulk portion.
