Abstract : The patent describes a process for treating 7000 series aluminum alloys whereby their stress-corrosion resistance is greatly increased. In accordance with the process, the alloy is pre-aged, deformed at room temperature, and then subjected to two aging steps. The alloy so treated has a high resistance to stress corrosion while retaining satisfactory strength properties.
