Abstract:

This investigation was undertaken to characterize the role of compositionmicrostructure 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.
