Forgings@ Aluminum Alloys 2xxx and 7xxx@ Heat-Treated@ Finished-Part Properties: Short-Transverse Tensile Properties and Fracture Toughness

AMS4335A-2017 发布历史

Form: This specification establishes requirements for 2xxx-series and 7xxx-series aluminum alloy forgings of any shape or form from which finished parts are to be made. (See 8.2@ 8.3@ 8.4@ 8.5.4@ 8.6 and 8.8.) Application: These forgings are used typically in the manufacture of high-performance parts when control of short-transverse tensile properties and fracture toughness is required@ but usage is not limited to such applications. These forgings are to be manufactured in accordance with a documented process. Product approval is based on first-article demonstrations of microstructural properties and of mechanical properties in the heat-treat condition and section size of the finished part. Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking after heat treatment. ARP823 recommends practices to minimize such conditions. Classification: Forgings shall be one of the following Types defined below and in Table 1@ as specified in the ordering data. (See 8.4.) When no Type is specified@ Type 2 shall be supplied. Type 1: For maximum acceptance testing and product uniformity. All requirements are preproduction tests@ all requirements excepting grain flow are acceptance tests@ and all of the forgings in a lot must be from the same lot of forging stock. (See 8.5.3.1.) Type 2: For maximum acceptance testing without maximum product uniformity. All requirements are preproduction tests@ all requirements excepting grain flow are acceptance tests@ and the forgings in a lot may be from different lots of forging stock. (See 8.5.3.2.) Type 3: For economic advantage so long as the forging manufacturer has a firmly-entrenched@ fairly sophisticated quality system. All requirements are preproduction tests@ tensile and fracture toughness tests are periodic tests (8.7)@ all other requirements excepting grain flow are acceptance tests@ and the forgings in a lot may be from the different lots of forging stock. (See 8.5.3.2.)
