- Abstract
The microstructure and the post-aging hardness of an Al - Li - Cu - Mg alloy is studied by the methods of transmission electron microscopy. Tensile tests are performed. The volume fraction and the size of the particles of the δ′, S and T phases are shown to be dependent on the aging temperature and time. The effect of the precipitates of the δ′, S and T phases on the hardening of the Al - Li - Cu - Mg alloy during aging is determined.
