  • Multilayered cellular metallic glass structures and methods of preparing the same
    Patent number: 8813339
    Abstract: Multi-layered cellular metallic glass structures and methods of preparing the same are provided. In one embodiment, the cellular metallic glass structure includes at least one patterned metallic glass sheet and at least one additional sheet. The at least one patterned metallic glass sheet may include multiple sheets connected together to form a group of sheets, and the structure may include a group of sheets sandwiched between two outer sheets. The patterned metallic glass sheets may be patterned by thermoplastically forming two- and/or three-dimensional patterns in the metallic glass sheets.
    Type: Grant
    Filed: September 21, 2012
    Date of Patent: August 26, 2014
    Assignee: California Institute of Technology
    Inventors: Robert D. Conner, Marios D. Demetriou, LeRoy A. Dunning, William L. Johnson
