AA 7050 Термическая Обработка
- 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 plate
Temper W51: Solution heat treated at 475°C, quenched, naturally aged. Stress-relieved by stretching is required to produce a specified amount of permanent set subsequent to solution heat treatment.
Temper T7451: Solution heat treated at 475°C, quenched, a two-stage treatment comprised of 3-6 hours at 120°C followed by 24-30 hours at 165°C. Stress-relieved by stretching is required to produce a specified amount of permanent set prior to any precipitation heat treatment.
Temper T7651: Solution heat treated at 475°C, quenched, a two-stage treatment comprised of 3-6 hours at 125°C followed by 12-15 hours at 165°C. Stress-relieved by stretching is required to produce a specified amount of permanent set prior to any precipitation heat treatment.
For rolled or cold finished wire and rod
Temper W: Solution heat treated at 475°C, quenched, naturally aged.
Temper T7: Solution heat treated at 475°C, quenched, a two-stage treatment comprised of 4 hours at 120°C followed by 6-8 hours at 180°C.
For extruded rod, bar and profiles
Temper W510: Solution heat treated at 475°C, quenched, naturally aged. Stress-relieved by stretching is required to produce a specified amount of permanent set subsequent to solution heat treatment.

Temper T73510: Solution heat treated at 475°C, quenched, a two-stage treatment comprised of 24 hours at 120°C followed by 10-14 hours at 175°C. Stress-relieved by stretching is required to produce a specified amount of permanent set prior to any precipitation heat treatment.
Temper T74510: Solution heat treated at 475°C, quenched, a two-stage treatment comprised of 24 hours at 120°C followed by 8-10 hours at 175°C. Stress-relieved by stretching is required to produce a specified amount of permanent set prior to any precipitation heat treatment.
Temper T76510: Solution heat treated at 475°C, quenched, a two-stage treatment comprised 4 hours at 120°C followed by 18-22 hours at 165°C. Stress-relieved by stretching is required to produce a specified amount of permanent set prior to any precipitation heat treatment.
Temper T73511: Solution heat treated at 475°C, quenched, a two-stage treatment comprised of 24 hours at 120°C followed by 10-14 hours at 175°C. Stress-relieved by stretching is required to produce a specified amount of permanent set prior to any precipitation heat treatment.
Temper T74511: Solution heat treated at 475°C, quenched, a two-stage treatment comprised of 24 hours at 120°C followed by 8-10 hours at 175°C. Stress-relieved by stretching is required to produce a specified amount of permanent set prior to any precipitation heat treatment.
Temper T76511: Solution heat treated at 475°C, quenched, a two-stage treatment comprised 4 hours at 120°C followed by 18-22 hours at 165°C. Stress-relieved by stretching is required to produce a specified amount of permanent set prior to any precipitation heat treatment.
For die forgings
Temper W: Solution heat treated at 475°C, quenched, naturally aged.
Temper T74: Solution heat treated at 475°C, quenched, a multi-stage treatment comprised of 8 hours at 105°C followed by 8 hours at 120°C followed by 4-10 hours at 175°C.
For hand forgings
Temper W52: Solution heat treated at 475°C, quenched, naturally aged. Stress-relieved by 1-5 percent cold reduction subsequent to solution heat treatment.
Temper T7452: Solution heat treated at 475°C, quenched, a multi-stage treatment comprised of 8 hours at 105°C followed by 8 hours at 120°C followed by 4-10 hours at 175°C. Stress-relieved by 1-5 percent cold reduction prior to precipitation heat treatment.
