  1. Hydrogen embrittlement of Aluminum-Lithium alloys

    Rivet, Frederic C.Virginia Tech1990

    … hydrogen on the mechanical properties of aluminum-lithium alloys: 2090, 2091, and Weldalite 049, and to compare with the effects on aluminum-copper 2219 alloy. Prior to mechanical testing, aging studies were performed for 2090 and 2219 using microhardness Vickers to determine the peak aged …

  2. Micromechanical models of delamination in aluminum-lithium alloys

    Messner, MarkUniversity of Illinois at Urbana-Champaign2014

    Aluminum lithium (Al-Li) alloys are lighter, stiffer, and tougher than conventional aerospace aluminum alloys. Replacing conventional aluminums with Al-Li could substantially decrease the weight and cost of aerospace structures. However, Al-Li alloys often fracture intergranularly via a mechanism …

  5. A parametric study of delaminations in an aluminum-lithium alloy

    Hamel, Sean F.University of Illinois at Urbana-Champaign2010

    … and increased strength have placed advanced aluminum-lithium alloys at the forefront of aerospace materials research. Delaminations in these alloys play a significant role in their fracture processes. Therefore, a more complete understanding of the factors that influence the behavior of these …

  6. Characterization of Delamination in 2099-T861 Aluminum-Lithium

    McDonald, Russell J.University of Illinois at Urbana-Champaign2010

    Aluminum-lithium alloys provide a lower density and higher stiffness alternative to other high strength aluminum alloys. However, many Al-Li alloys exhibit a non-traditional failure mechanism, delamination. Delamination refers to the failure along the grain boundary interface. The delamination …
