  • Methods of structural health monitoring using metal bodies containing microcavities
    Patent number: 8756815
    Abstract: Monolithic metal bodies (e.g., hard aluminum alloys) comprising a continuous microcavity contained within the body are disclosed. The ratio of the cross-sectional area of the metal body to the cross-sectional area of the microcavity may be not greater than 10. The produced metal bodies may be used in structural applications (e.g., aerospace vehicles) to monitor or test the integrity of the metal body.
    Type: Grant
    Filed: September 11, 2012
    Date of Patent: June 24, 2014
    Assignee: Alcoa Inc.
    Inventors: Hasso Weiland, Markus Heinimann, Robert C. Pahl, Achim Hofmann, John Liu

  • MULTI-ALLOY MONOLITHIC EXTRUDED STRUCTURAL MEMBER AND METHOD OF PRODUCING THEREOF
    Publication number: 20070128463
    Abstract: The present invention provides a structural member of a multi-alloy monolithic extrusion comprising a first aluminum alloy and a second aluminum alloy; wherein the first aluminum alloy is metallurgically fused to the second aluminum alloy. In another aspect of the present invention, an extrusion method is provided including the steps of providing a first billet and at least a second billet; machining the first billet to form a first substantially flat surface; machining the second billet to form a second flat surface; positioning the first flat surface of the first billet adjacent to the second flat surface of the second billet; welding at least a portion of the first billet to the second billet to form a third billet; and extruding the third billet to form a monolithic multi-alloy structural member.
