QUALITY ASSURANCE PROVISIONS: See AMS-QQ-A-250 and the following:4.1 Heat Treatment: 4.1.1 Aging Period Before Testing: Specimens in the T31, T351, and T37 tempers shall not be required to be tested within 4 days after completion of the hea

39、t treatment. If the manufacturer so elects, samples may be tested after less than 4 days aging; but if they fail to meet specified properties, the test samples may be discarded and additional specimens may be tested after 4 days aging. These specimens shall be taken from the same locations in the pr

40、oduction lot or sample from which the prior specimens were taken.4.2 Mechanical Tests After Heat Treatment: 4.2.1 Number of Tests After Heat Treatment: From material in each temper of those specified for heat treatment capability demonstrations in 3.2.2 and 6.2, an additional number of specimens equ

41、al to that required in AMS-QQ-A-250 shall be taken and tested after heat treatment to each temper specified to determine conformance to 3.2.2.4.3 Stress-Corrosion Cracking Test: Samples of plate in the thicknesses and tempers identified in 3.4 shall be taken in accordance with AMS-QQ-A-250. Test spe

42、cimens shall be selected in a manner that will permit application of the specified tensile stress in the short-transverse direction with respect to grain flow. Specimens shall be stressed in tension in the short-transverse direction and be held at constant strain. The stress level shall be 75 percen

43、t of the long-transverse yield strength. The specimens shall be subjected to the stress-corrosion test specified in AMS-QQ-A-250.4.4 Records: It is the responsibility of the contractor that all test results be recorded, identified as to inspection lot, and preserved after completion of the contract

45、TIONAL AMS-QQ-A-250/30A Page 7 of 8 6. NOTES:6.1 Intended Use: Aluminum alloy 2219 plate and sheet is intended for use where elevated temperature strength is required. This alloy is also noted for its good weldability and stress-corrosion resistance in the artificially aged tempers. Use of material

46、in the T31, T351, and T37 tempers is not recommended for finished products when optimum corrosion resistance is required.6.2 Properties After Heat Treatment: Mechanical and corrosion properties of producer-supplied material are certified for the temper of material supplied. The producers capability

47、demonstration is not evidence that user-treated material conforms to property requirements of a given temper. Frequently, user-heat-treated material may develop a lower level of properties, especially if any cold, warm, or hot work is introduced prior to solution heat treatment. The user should be h

48、eld responsible for demonstrating that his processing meets strength and corrosion requirements.6.3 Temper: Tempers T351 and T851 are available in plate only.6.4 Ordering Data: Purchasers should select the preferred options permitted herein and include the following information in procurement documents:Title, number, and date of this specification.Form, quantity, and temper required (See 1.2.1).Dimensions required.Requirements for sizes not specifically covered (See AMS-QQ-A-250).Whether ultrasonic inspect
