Door opening durations greater than two minutes are permitted provided the time between the door opening and recovery of furnace temperature is not included in the total time.

3.3 Solution Heat Treating - Heating and Soaking

3.3.1 Temperature

Parts that require solution heat treatment shall be soaked at the temperature specified in Table 2.

3.3.2 Furnace Temperature Stabilization

3.3.2.1 For air furnace loads where the previous load was at a higher set temperature, or the prior temperature

uniformity test was in a loaded furnace, furnaces shall be stabilized at the new set temperature before loading parts.

3.3.2.2 If the prior temperature uniformity test was in an unloaded furnace, furnace loads of non-clad material may be

loaded in a cold furnace or furnace whose previous set temperature was below the new set temperature.

3.3.2.3 For parts made from alclad material, furnaces shall be stabilized at the set temperature before loading parts.

3.3.3 Prevention of Hydrogen Induced Porosity

Entrapped water shall be prevented from entering the furnace. Ammonium fluoborate, or equivalent, should be used in air furnaces as necessary, however, purging the furnace with fresh air may be necessary to prevent discoloration of subsequent loads of parts made from alclad product.

3.3.4 Recovery Time for Alclad Parts

For solution heat treating of parts made from alclad product under 0.125 inch (3.18 mm) thick, the furnace recovery time shall not exceed 30 minutes and for parts made from heavier Alclad product, shall not exceed 60 minutes.

3.3.5 Multiple Solution Heat Treatments of Alclad Product

Parts made from product over 0.125 inch (3.18 mm) in nominal thickness shall be limited to two solution heat treatments in addition to any by the material producer. Parts made from product 0.020 to 0.125 inch (0.51 to 3.18 mm) in nominal thickness, shall be limited to one additional solution heat treatment in addition to any by the raw material producer. For parts made from product under 0.020 inch (0.51 mm) in nominal thickness, additional solution heat treatments are prohibited.

3.4 Solution Heat Treating - Quenching

3.4.1 Following completion of the required soaking, parts shall be quenched by immersion in water or in a

water/polymer solution conforming to the requirements of Table 4, except where the use of alternate quenched media is allowed for 6xxx series alloy parts per 3.4.6. Parts are in the AQ (as-quenched) temper immediately after quenching (See 8.8.7).

Temperature

3.4.2 Quenchant

At the start of quench, quenchant temperature shall not exceed 90 °F (32 °C) except when water quenching parts made from forgings. When quenching parts made from forgings, the start of quench water temperature shall conform to Table 1.

3.4.6 Quenchants Other Than Water or Water/Polymer Solutions for 6061, 6063, 6066 and 6951 Alloy Parts

Thin parts under 0.125 inch (3.18 mm) in nominal thickness, made from 6061, 6063, 6066 and 6951 alloys, may be quenched in an air blast, water spray or fog, providing that the quality assurance provisions specified herein are supplemented by tensile and hardness tests as specified in 4.3.1.2.2.

3.4.7 Immersion

Time

Parts racked or in baskets shall be kept immersed in the quenchant for not less than one minute per inch (25.4 mm) of maximum thickness, or fraction thereof, or for not less than one minute after all evidence of boiling ceases, whichever is longer. Sheet metal parts less than 0.125 inch (3.18 mm) thick may be removed from the quenchant as soon as all boiling ceases.

3.4.8 When water quenching from a salt bath, if the water quench tank does not have an overflow system to preclude

salt build-up in the quench tank, parts shall be rinsed in fresh water to preclude the possibility of salt residue on parts.

Solutions

3.4.9 Water/Polymer

3.4.9.1 Water/polymer solutions shall conform to AMS 3025, Type 1 or Type 2. Concentrations shall comply with Table

4. The pH of water/polymer solutions shall be maintained between 7.5 and 8.7.

3.4.9.2 After quenching into a water/polymer solution, parts shall be thoroughly rinsed with fresh water to remove the

residual polymer.

3.4.9.3 Polymer Concentration Control

Methods

3.4.9.3.1 Test

Determination of concentration shall be based on tests of viscosity (in accordance with ASTM D 445) or by refractive index using a refractometer, e.g. °Brix, glycol coolant, salinity, specific gravity, Abbe, etc., calibrated in accordance with 3.4.9.3.6. A refractometer scaled in °Brix is preferred.

Frequency

3.4.9.3.2 Test

Concentration shall be determined quarterly by viscosity. In addition, concentration shall be determined weekly, and when concentration is changed, by viscosity or refractive index.

3.4.9.3.3 When refractometer concentration measurement is made, the concentration of the tank shall be recorded as

the value determined by the corrected refractive index measurement (See 3.4.9.3.6).

3.4.9.3.3.1 Quenchants Used With Salt Bath Furnaces

When a refractometer is used, and a test of the quenchant shows that its salt content has changed by 1% or more since the last viscosity test, a new multiplying factor shall be determined (See 3.4.9.3.6.3) . Determination of the new multiplying factor shall be based on a new viscosity test or calibration against solutions of similar concentration in accordance with 3.4.9.3.4.

3.4.9.3.4 When a viscosity concentration measurement is taken, the reading shall be compared to the corrected

refractive index concentration measurement (See 3.4.9.3.6) taken on the same sample. For the purpose of

comparison, the viscosity value and refractive index value shall be rounded to the nearest 0.5% polymer

concentration. If the concentration value of the two measurements differ by 2% or less, the concentration of

the tank shall be recorded as the value determined by the refractive index measurement. If the rounded

corrected concentration values of the two measurements differ by more than 2%, the reasons for the variance

shall be determined and corrective action taken.

3.4.9.3.5 Equipment

3.4.9.3.5.1 Refractometers use for determination of concentration shall be temperature compensating, and of a range

suitable for the concentration being measured.

3.4.9.3.5.2 Refractometers, when checked against standards, shall have a measurement accuracy of ± 0.5% polymer

or ± 0.3° Brix as applicable, with a scale resolution or minimum indication of ± 0.2° Brix (or equivalent).

3.4.9.3.6 Calibration of Refractometers

3.4.9.3.6.1 Refractometers shall be calibrated at 90-day intervals. The method of calibration shall be documented, and

a seal stating the date of calibration shall be affixed to the refractometer.

A

3.4.9.3.6.2 Method

Refractometers may be calibrated against prepared polymer solutions of known composition. The calibration solutions may be prepared either by a volumetric or a weight method. Calibration points shall bracket each concentration and shall be within 2% of the tank concentration to be measured. The tank concentration shall be determined by adjusting the refractometer reading according to a calibration factor, curve or table resulting from the calibration.

B

3.4.9.3.6.3 Method

Refractometers may be calibrated against known refractive index standards. These standards can be created using carefully weighed amounts of sucrose in water. Alternatively, NIST traceable refractive index standards can be purchased (such as °Brix or refractive index prisms). Three points (zero, midpoint and span of the refractometer) are required. Concentration of either AMS 3025 Type 1 or Type 2 polyalkalene glycol (PAG) is determined by dividing the reading on the refractometer by the concentration of the same sample determined by viscosity. This multiplying factor is then applied to subsequent concentration determinations by refractometer. A new multiplication factor is determined at each concentration determination by viscosity in accordance with ASTM D 445.

3.4.9.3.6.4 The calibration curve for each specific fluid shall accompany each refractometer.

3.4.9.3.6.5 For quenchants used with salt bath furnaces, the calibrating solutions shall contain known amounts of salt,

and the calibration method shall incorporate the effects of the salt.

3.4.9.3.6.6 Alternative Calibration Methods

Calibration methods different from 3.4.9.3.6.2 or 3.4.9.3.6.3 may be utilized when approved by the cognizant engineering organization.

Contamination

3.4.9.4 Salt

Salt content in polymer/water quenchants shall not exceed 6.0% by weight. Water/polymer quenchants used with salt bath furnaces shall be tested for salt content weekly. The method used shall be calibrated against solutions containing known amounts of both polymer and salt, and the procedure documented. Meters used to determine the salt concentration shall be calibrated every 90 days. Quench tanks which exceed 6.0% salt content shall not be used until the salt content has been reduced below 6% or the quenchant has been replaced.

3.5 Refrigeration

3.5.1 Parts requiring retention of the as quenched (AQ) condition after solution heat treatment shall, after quenching, be

refrigerated in conformance with the requirements of Table 6.

3.5.2 Prechilling

Prior to refrigeration, parts may be prechilled by immersion in a cooled liquid to accelerate cooling.

3.6 Aging

3.6.1 Parts requiring aging shall be aged as specified in Table 7.

3.6.2 Straightening After Aging

Straightening of parts in the following tempers is prohibited unless approved by the cognizant engineering organization: T6, T6X, T7, T7X, T8 and T8X as well as parts in the T4 and T4X tempers which have aged sufficiently at room

temperature to meet either the hardness or conductivity minimum of AMS 2658.

3.7 Annealing and Stress Relieving

3.7.1 Parts requiring annealing shall be heated, soaked and cooled as specified in Table 8.

3.7.2 A full anneal shall be used unless the treatment specified is a partial anneal or stress relief.

3.7.3 Except for material in the solution heat treated or aged condition, if a stress relief or stress relief treatment is

specified, the partial anneal parameters of Table 8 shall be used. The partial anneal (stress relief) treatments in Table 8 shall not be used to relieve residual stress in parts in the solution heat treated or aged condition.

3.8 O1 (Formerly T411) Temper

Parts required to be in the O1 temper shall be heated to the solution heat treating temperature specified in Table 2, soaked for the time specified in Table 3, and air cooled to room temperature.

3.9 Logs

A record (written or electronic storage media), traceable to temperature recording information (chart(s) or electronic storage media) and to shop travelers or other documentation, shall be kept for each furnace and load. The information on the combination of documents shall include: equipment identification, approved personnel’s identification, date; part number or product identification, number of parts, alloy, lot identification, AMS 2770 (or other applicable specification), actual thermal processing times and temperatures used. When applicable, atmosphere, quench delay, quenchant type, polymer concentration, and quenchant temperature shall also be recorded. The maximum thickness, when process parameters are based on thickness, shall be recorded and shall be taken as the minimum dimension of the heaviest section of the part. The log data shall be recorded in accordance with the heat treater’s documented procedures.

3.10 Temper Conversion

When a warehouse, distributor or similar organization converts raw material to a different temper, it shall be heat treated and tested in accordance with the requirements of this specification. The marking, testing and reporting shall be in accordance with AMS 2772 and the material specification.

Records shall be kept available for five years after heat treatment. The records shall contain all data necessary to verify conformance to the requirements of this specification.

4.3 Parts Control

4.3.1 Parts Other Than Rivets and Similar Small Standard Parts

Shall be tested in accordance with the following:

4.3.1.1 7xxx Alloy Parts in T7X Tempers

Every part shall be conductivity tested at the thickest section. Additionally, every part shall be hardness tested except, when approved by the cognizant engineering organization, hardness testing frequency may be reduced to not less than 25%. (Parts which exhibit low conductivity and/or high hardness may be given additional aging (See Table 7) and retested).

4.3.1.2 6061, 6063, 6066 and 6951 Alloy Parts

Every part shall be hardness tested. 6061, 6063, 6066 and 6951 alloy parts should not be conductivity tested and shall not be rejected for failure to meet conductivity requirements of AMS 2658.

4.3.1.2.1 6013 alloy parts shall be tested in accordance with 4.3.1.3.

4.3.1.2.2 Air Blast, Water Spray or Fog Quenched 6xxx Series Alloy Parts (See 3.4.6)

In addition to hardness testing in accordance with 4.3.1.2, tensile specimens shall be taken from each heat treat load. The specimens may be made from parts having the lowest hardness, or sample material representing the thickest section of the parts, located near the center of the load. Tensile properties shall conform to the applicable material specification.

4.3.1.3 Other Alloys or Other Tempers

Each lot (See 8.8.10) of parts in a “T” temper shall be hardness and conductivity tested. (Hardness and conductivity testing is not required for parts in the annealed or stress relieved condition.) Testing shall be in accordance with 4.3.1.3.1 or 4.3.1.3.2.

4.3.1.3.1 Every part shall be hardness tested and 10% of the parts shall be conductivity tested. The conductivity tested

parts should include those having the highest and lowest hardness.

4.3.1.3.2 Every part shall be conductivity tested and 10% of the parts shall be hardness tested. The hardness tested

parts should include those having the highest and lowest conductivity.

4.3.1.3.3 Tensile or Shear Testing

Alternatively, when tensile or shear testing is required, it may be substituted for the 10% hardness testing. Specimen(s) shall be made from a part selected at random, or a prolongation thereof, or from a sample of the product from which the parts were fabricated. The specimen(s) shall represent the maximum thickness of each lot of parts in each heat treat load. If any test result fails to meet to the applicable requirements, the entire lot shall be rejected and referred to the customer for disposition.

4.3.1.3.4 Sampling and Testing

In lieu of testing each part in accordance with 4.3.1.3.1 or 4.3.1.3.2, random samples of each lot may be tested for both hardness and conductivity when sampling is approved by the cognizant quality assurance organization. The sampling frequency shall not be less than 25 percent.

4.3.1.4 Testing and acceptance criteria for parts whose size or shape does not permit hardness or conductivity testing

shall be as follows:

4.3.1.4.1 Either the hardness or conductivity testing may be omitted provided every part is tested by the remaining

method. If this option is used, the report shall reflect that the parts could not be hardness (or conductivity)

tested due to size or shape, and that all parts were conductivity (or hardness) tested.

4.3.1.4.2 If parts can neither be hardness nor conductivity tested, testing and acceptance criteria shall be as specified

by the cognizant quality assurance organization.

4.3.2 Rivets and Similar Small Standard Parts

If mechanical testing (e.g., tensile, shear) is not required on each lot, hardness testing is required on each lot of parts. In addition, conductivity testing is required on each lot of 7xxx alloy parts. Sampling shall be at the same frequency as required for the strength parameter by the part specification or drawing. For parts whose size or configuration precludes the above testing, representative (in alloy, thickness, and temper) coupons shall be tested based on furnace used as follows:

4.3.2.1 Parts Solution Heat Treated and Aged in Batch Type Furnaces

A minimum of three test coupons per lot shall have been randomly placed in each solution heat treatment and age load.

4.3.2.2 Parts Solution Heat Treated and/or Aged in Continuous Furnaces

A minimum of one test coupon per lot shall have been placed in each solution heat treating and aging furnace during each shift or twelve hours, whichever is less.

4.3.3 Failures

If any part or coupon fails to meet either hardness or conductivity requirements of AMS 2658, every part (which can be tested) in the lot shall be tested. Parts, and parts represented by coupons, which fail to meet either requirement shall be rejected and referred to the customer for disposition.

4.4 Report/Certification

The heat treating processor shall furnish, with each shipment of parts, a certified quality assurance report, traceable to the heat treat control number(s), stating that the parts were processed in accordance with the requirements of AMS 2770 (or other applicable specification).

Production heat treatment by material producers and forge shops, or their vendors, of products listed below should be performed in accordance with the procurement specification and/or AMS 2772 (See 8.8.8). Products applicable to AMS 2772 are: Sheet, Plate, Foil, Bar, Rod, Wire, Extruded Shapes, and Forgings.

8.3 Use of Load Sensors

The mandatory soaking times for air furnace solution heat treatment (Table 3) and aging (Table 7) are based on using control sensors reflecting furnace air temperature. They include allowance for the lag between air temperature and metal temperature. Therefore basing the start of soaking on load sensors, and soaking for the Table 3 and 7 times, will result in excess soaking time. In the case of aging, this may result in reduced properties; in the case of solution heat treatment, it will increase clad diffusion. Use of load sensors should be limited to confirming that parts reached and, during soaking, remained within the allowable range, i.e., the range defined by applying the furnace temperature uniformity tolerance to the specified temperature.

8.4 Solution heat treatment soak times include allowances for the more uniform temperature distribution in salt

baths/fluidized beds than air furnaces and the extra lag time needed for part temperatures to reach the heating medium temperature in air furnaces.

8.5 Mill Furnished Tempers

The tempers listed below are normally furnished by producers and cannot be produced by users. Consequently, parts for which product in one of these tempers is specified should not be re-solution heat treated, annealed, or heat treated to the O1 (formerly T411) temper unless authorized by the cognizant engineering organization:

T3, T31, T36, T361, T37, T81, T86, T87, T351, T451, T651, T851, T861, T3510, T3511, T4510, T4511, T6510, T6511, T8510, T8511, T7651, T7351, T76510, T73510, T73511, T736510, T736511, T652, T654, T7352, T7354, T73651, T73652, T73654, T7451, T7452, T7454, T74510, T74511.

8.6 T736XX temper designations have been superseded by T74XX temper.

8.7 Aluminum Alloy Tempers are described in AS1990.

8.8 Terms used in AMS are clarified in ARP1917 and as follows:

8.8.1 Parts Heat Treatment

Heat treatment by a source other than the raw material producer. Product is tested to the requirements of the heat treat processing specification or to selected requirements of other specifications (See 8.8.8). Rivets are considered parts at any stage of manufacture.

8.8.2 Solution Heat Treatment

Heating an alloy at an elevated suitable temperature for sufficient time to allow soluble constituents to enter into solid solution where they are retained in a supersaturated state after quenching.

8.8.3 Aging (Precipitation Heat Treatment)

Soaking solution heat treated parts at a moderately elevated temperature or, for some alloys and tempers, at room temperature to enhance strength and corrosion resistance properties.

8.8.4 Annealing

A thermal treatment used to soften metal. A full anneal will soften product to develop maximum formability and ductility. A partial anneal (stress relief) is used when grain growth is a problem or when less formability or ductility than provided by a full anneal is acceptable.

Quenchant

8.8.5 Polymer

A water solution of polymer used to alter the quench rate, intended to minimize distortion and residual stresses.

8.8.6 O1 (formerly T411) Temper

A special annealed condition used to minimize warpage during machining. Response to ultrasonic inspection is better than with “F” or “O” temper product. This is not a final temper.

8.8.7 AQ Temper After Quenching

All alloys are in the AQ (as-quenched) temper immediately after quenching. After maximum delay time at room temperature or maximum refrigerated storage time (as listed in Table 6) has elapsed, they are in the W temper which is unstable, i.e., their properties are continually changing. After 96 hours, of room temperature aging, the 2xxx and 6xxx alloys achieve stable, or relatively stable, T4 or T42 tempers.

8.8.8 Raw Material (e.g., Sheet, Plate, Bar, Extrusions, Forgings, Castings)

Heat treatment is performed by or for the raw material producer and product is tested as required by the material specification (See 8.8.1).

8.8.9 Cognizant

A term applied to the engineering organization responsible for the design of the parts, its allied quality assurance organization, or a designee of those organizations.

8.8.10 Lot

A group of parts of the same part number and at the same stage of fabrication which have been either heat treated in the same load or, in the case of continuous furnaces, hand loaded salt baths, etc., have been heat treated continuously during a single shift, not to exceed a twelve hour period.

8.8.11 Recovery Time

The elapsed time between insertion of parts in a heating medium and start of soaking time.

8.8.12 Large Plan Form

A part which has a large planer surface area in relation to its thickness such as a plate or sheet.

8.9 Dimensions and properties in inch/pound units and the Fahrenheit temperatures are primary; dimensions and

properties in SI units and the Celsius temperatures are shown as approximate equivalents of the primary units and are presented only for information.

Notes:

1. The aging treatment for 7049, 7149 and 7249 alloys shall not be initiated until at least 48 hours at room

temperature have elapsed after quenching.

2. To avoid stress corrosion cracking of thick 7049, 7149, 7249 and 7050 parts, delay between quenching and start of

aging should not exceed 72 hours.

3. The 0.05 inch (1.3 mm) dimension refers to thickness at time of heat treatment.

4. If heat treater can positively identify the original raw stock as sheet or plate having a thickness of 0.05 to1.0 inch

(1.3 to 25 mm), inclusive, 920 °F (493 °C) may be used.

5. After normal soaking, increase temperature to 920 °F (493 °C) for alclad and 955 °F (513 °C) for non clad;

minimum soaking time at higher temperatures, 15 minutes and 60 minutes, respectively.

6. 870 °F is the preferred treatment to achieve adequate hardness and conductivity readings but 920 °F (493 °C) may

be used to improve tensile properties.

7. Solution heat treat temperatures as low as 870 °F (466 °C) may be used to control recrystallization and surface

cracking problems.

8. For 6061, an alternate solution heat treating temperature of 995 °F (535 °C) may be used.

9. Rivets, which are to be aged to the T73 temper may be solution heat treated at 875 °F (469 °C).

10. Should not be solution heat treated after forming because it has a tendency to develop a large grain structure due

to recrystallization.

11. Eutectic melting may occur at the specified temperature if the raw material was not properly homogenized or

worked.

12. Applies to clad brazing sheet #21 and #22 - core is 6951 alloy.

Notes for Table 7 - Aging Treatments:

1. (M) Mandatory, (P) Preferred or (A) Alternate Aging Treatment.

2. Digits added to these basic temper designations to denote stress relief treatments etc. should appear identical before

and after aging.

3. Either second step age may be used with either first step age interchangeably.

4. For all T7XX tempers, the first step of the T7XX age may be omitted if parts (material) are (is) in the T6 temper.

5. When temper before furnace aging is AQ, W, T4, or T42, the furnace aging treatment may be started immediately

after quenching or at any time thereafter. With the exception of 7049, 7149 and 7249 alloys, natural aging is not

necessary before initiating a -T6XX or the first step of -T7XX age.

6. The aging treatment for 7049, 7149 and 7249 parts shall not be initiated until at least 48 hours after quenching. To

avoid stress corrosion cracking of thick 7049, 7149, 7249 and 7050 parts, the elapsed time between quenching and

start of aging should not exceed 72 hours.

7. 14 to 15 hours if thicker than 2 inches (51 mm).

8. Longer aging times, not exceeding a total of 4 additional hours (6 additional hours for 7050 forgings thinner than

0.260 inches (6.60 mm), at the specified second step temperature are permissible to reduce hardness and/or raise

conductivity of T7XX parts in order to meet AMS 2658 requirements.

9. Formerly designated T736.

10. T4 is achieved when hardness and conductivity per AMS 2658 are met. Typically, this is achieved within 96 hours at

room temperature.

11. Applies to clad brazing sheet #21 and #22 - core is 6951 alloy.

12. Soaking time shall conform to 3.2.5. All soaking times,except those for 7050 alloy and those referencing note 7, are for

product or nested stack up to 0.5 inch (12.7 mm) thickness (minimum dimension of heaviest section). Add 0.5 hours to times for each additional 0.5 inch (12.7 mm) or fraction thereof. Soaking times shown are applicable to all thicknesses of 7050 alloy. When using load thermocouples to measure aging time, the soaking times for the 0.5 inch product shall apply.

13. Aging temperature and times for stress relieved tempers, TX5, TX51, TX51X and TX52 shall be the same as basic temperatures .
