AA 2618 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.

    For forgings and rolled rings

    Temper T4: Solution heat treated at 535°C, quenched in water at 100°C, naturally aged. By definition, this temper designation is that which would apply after natural aging even though mechanical properties for this alloy-temper product have not been registered.

    Temper T61: Solution heat treated at 535°C, quenched in water at 100°C, precipitation heat treated at 200°C for 20 hours.
