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.)
