The natural aging behavior of the AA 2055 Al-Cu-Li alloy

The Al-Cu-Li alloys are of the interest of many aircraft engineers, as they are superior to conventional Al alloys, used in the aircraft industry. The AA 2055 alloy exhibit an outstanding combination of mechanical properties, the high modulus of elasticity and the low density. Even those alloys are standardly used in the artificial aged conditions; the natural aged state can show significant improvement in the ductility, sacrificing some of the strength. In the presented paper, the natural aging behavior of the AA 2055 alloy is characterized, in terms of the mechanical properties and thermodynamic stability.
