Update specification. Ballot for AMEC only.

The purpose of this standard is to provide uniform methods for defining, quantifying and classifying the residual stress in metallic structural alloy products and finished parts. Such quantification and classification may be required when residual stresses within preforms can impact further in-process distortion during machining or other processes, and when residual stresses within finished components can impact final mechanical properties and performance.

Incorporate into AMS2750 the requirements for pyrometry associated with composites.

Review AMS2770 or create a new AMS for the heat treatment of brazed assemblies.

New AMS for the test methods to be used for the Verification of Aluminum Alloys using Eddy Current Methods.

AMEC only ballot for 5 year review and update.

The objective of this program is to compare the properties of aus-bay quenched 300M steel with the properties of 300M steel oil quenched in the conventional manner.

An analysis was made of the effects of various surface conditions on the heat up time of steel bars which are heated in atmosphere furnaces to the temperature range used for steel hardening or normalizing. The purpose was to examine whether a standard heating time for a given section thickness is acceptable.

Performed tensile and fatigue tests on bolts to determine if cutting of materials flow lines at the bolt underhead would degrade bolt integrity. Five different alloys used in aerospace industry fatigue critical applications were employed to fabricate 5/16 to 1/2 inch diameter bolts. These bolts were machined from bar stock producing fully cut material flow lines under their heads. Tensile testing with and without underhead washers was performed along with industry standard fatigue testing.

This Aerospace Standard (AS) establishes the requirements for suppliers of Shot Peening Services to be accredited by the National Aerospace and Defense Contractors Accreditation Program (NADCAP). NADCAP accreditation is granted in accordance with SAE AS7003 after demonstration of compliance with the requirements herein. The requirements may be supplemented by additional requirements specified by the NADCAP Nonconventional Machining and Surface Enhancement (NMSE) Task Group. Using the corresponding Audit Criteria (PRI AC7117) will ensure that accredited Shot Peening suppliers meet all of the requirements in this standard and all applicable supplementary standards. The purpose of this audit program is to assess a supplier's ability to consistently provide a product or service that conforms to the technical specifications and customer requirements.

The complete requirements for procuring the product shall consist of this document and the latest issue of the basic specification, AMS 2431.

An analysis was made of the effects of various surface conditions on the heat up time of steel bars which are heated in atmosphere furnaces to the temperature range used for steel hardening or normalizing. The purpose was to examine whether a standard heating time for a given section thickness is acceptable.

This specification covers the engineering requirements for peening surfaces of parts by impingement of metallic shot, glass beads, and ceramic shot. To induce residual compressive stress in surface layers of parts, thereby increasing fatigue strength and resistance to stress corrosion cracking.
