AA 2024 Heat Treatments

  • The times and temperatures are typical for various forms, sizes and methods of manufacture and may not exactly describe the optimum treatment for a specific item.

    The nominal temperatures at which metal is heated (applies both for solution and precipitation heat treatment) should be attained as rapidly as possible and maintained ± 5°C of nominal during the time at temperature.

    The time at precipitation heat treatment temperature will depend on time required for load to reach temperature. The times shown are based on rapid heating, with soaking time measured from the time the load reached within 5°C of the applicable temperature.

    Material should be quenched from the solution heat-treating temperature as rapidly as possible and with minimum delay after removal from the furnace. Quenching is typically performed by immersion of wrought products in a cold water bath, although some forgings are quenched in hot-water. Quenching may be performed by alternative means such as total immersion in an aqueous polymer solution, liquefied gas, hot water, or boiling water, or by air blast or fog to minimize distortion provided samples from the material. The use of high-velocity high-volume jets of cold water is also effective for some materials.

    Temper T8511: Solution heat treated at 495°C, quenched, precipitation heat treated at 190°C, for 12 hours. Stress-relieved by stretching is required to produce a specified amount of permanent set prior to any precipitation heat treatment.

    For drawn tube

    Temper T3: Solution heat treated at 495°C, quenched, naturally aged. Cold work subsequent to solution heat treatment is required to attain the specified mechanical properties for this temper.

    Temper T42: Solution heat treated at 495°C, quenched, naturally aged.

    Annealing (O)

    Heated at 415°C, held for 2-3 hours. This treatment is intended to remove effects of solution heat treatment and include cooling at a rate of about 30°C per hour from the annealing temperature to 260°C. The rate of subsequent cooling is unimportant. Treatment at 345°C, followed by uncontrolled cooling, may be used to remove the effects of cold work, or to partially remove the effects of heat treatment.
