  • Methods of aging aluminum alloys to achieve improved ballistics performance
    Patent number: 8758530
    Abstract: Aluminum alloy products having improved ballistics performance are disclosed. The aluminum alloy products may be underaged. In one embodiment, the underaged aluminum alloy products realize an FSP resistance that it is better than that of a peak strength aged version of the aluminum alloy product. In one embodiment, ballistics performance criteria is selected and the aluminum alloy product is underaged an amount sufficient to achieve a ballistics performance that is at least as good as the ballistics performance criteria.
    Type: Grant
    Filed: September 3, 2010
    Date of Patent: June 24, 2014
    Assignee: Alcoa Inc.
    Inventors: Roberto J. Rioja, Dirk C. Mooy, Jiantao T. Liu, Francine S. Bovard
