SAE 7049 Heat Treatments

High temperature annealed (at solution heat treat temperature) in accordance with MILH- 6088 except that forgings shall be ambient air cooled to room temperature.
Solution heat treating at 468°C for all forms (the aging treatment for 7049 alloy shall not be initiated until at least 48h at room temperature have elapsed after quenching),( to avoid stress corrosion cracking of thick 7049 parts, delay between quenching and start of aging should not exceed 72h).
Solution heat treating soaking times and maximum quench delay times is on specifications.
Limits for quenching in polymer solutions for sheets, plates, bars: for thickness 2.03 mm polymer concentration is 40% max (±2); for thickness 6.35 mm polymer concentration is 34% max (±2); for thickness 9.52 mm polymer concentration is 28% max (±2); for thickness 12.70 mm polymer concentration is 22% max (±2); for thickness 25.40 mm polymer concentration is 16% max (±2). Limits for quenching in polymer solutions for forgings: for thickness 25.40 mm polymer concentration is 18-22% max (±2); for thickness 50.80 mm polymer concentration is 11-15% max (±2); for thickness 76.20 mm polymer concentration is 8-12% max (±2). Limits for quenching in polymer solutions for extrusions: for thickness 6.35 mm polymer concentration is 28% max (±2); for thickness 9.52 mm polymer concentration is 22% max (±2). Aging treatment is mandatory. For extruded bars and shapes: Starting temper is W, final temper is T73 (sometimes used to designate final tempers), 1st step: aging at 121°C for 23-25h, 2nd step: aging at 166°C for 21-22h (14-15h if thicker than 51mm); Starting temper is W, final temper is T76 (sometimes used to designate final tempers), 1st step: aging at 121°C for 23-25h, 2nd step: aging at 166°C for 14-15h. For forgings: Starting temper is W, final temper is T73 (sometimes used to designate final tempers), 1st step: aging at 121°C for 23-25h, 2nd step: aging at 166°C for 13-14h.
Full anneal: At 399-427°C, soaking time is minimum 2h (soak times listed are for up to 13 mm maximum thickness. Add 0.5 hour for each additional 13 mm of product or nested stack thickness or fraction thereof over 13 mm), cooling in furnace (furnace cool at 28°C degrees per hour maximum, to 232°C, hold at 232°C for 6 hours, furnace or air cool to room temperature). Stress relief: At 333-349°C, soaking time is minimum 2h (soak times listed are for up to 13 mm maximum thickness. Add 0.5 hour for each additional 13 mm of product or nested stack thickness or fraction thereof over 13 mm), cooling in air.
