Resistance to Fracture, Fatigue and Stress-Corrosion of Al-Cu-Li-Zr Alloys

Abstract

This investigation was undertaken to characterize the role of composition/microstructure on the mechanical behavior of Al-Cu-Li-Zr alloys. This characterization is intended to serve as a baseline data for alloy development work directed at improving the mechanical properties of Al-Li alloys. The report summarizes the results on fracture, fatigue and stress corrosion behavior of Al-Cu-Li-Zr alloys. Originator keywords: 7075, 2020, Hydrogen, Composition, Aging treatment, Microstructure, Microscopy, Texture, Fracture, Stress corrosion, Fractography, Fatigue crack growth, Constant amplitude, Spectrum loading.
