Abstract:
New methods of making cold formed, extruded aluminum lithium alloys, and unrecrystallized products made therefrom are disclosed. A method may include one or more of heating an unrecrystallized extruded aluminum-lithium product to a treatment temperature, cooling the unrecrystallized extruded aluminum-lithium product from the treatment temperature to a post-treatment temperature, and cold forming the unrecrystallized extruded aluminum-lithium product into a second product form. Due to the unique processing conditions of the method, the second product form may wholly or partially retain the unrecrystallized microstructure.
