Abstract:

The paper presents results on fatigue properties of Al-Li 8090 plate material generated at Deutsche Forschungs-und Versuchsantalt fur Luft- und Raumfahrt, National Lucht-en Ruimtevaartlaboratorium and Royal Aerospace Establishment in the frame of Group for Aeronautical Research and Technology in Europe activity on Al-Li alloys. High cycle fatigue results are discussed as well as fatigue crack growth properties. Comparison is made to conventional high strength Al alloys. In most cases the Al-Li alloy showed at least equivalent high cycle fatigue properties and improved resistance to fatigue crack growth, primarily due to crack closure effects.
