Complete revision of AMS2750E.

Temporary AMEC project to revise AMS2774.

This project is to development the heat treatment of Ni & Co additive manufactured parts.

This project is temporary for the purposes of balloting ARP1962 to AMEC only. When finished within AMEC it will formally be balloted to B.

AMEC only ballot for 5 year review and update.

Temporary document for the purposes of balloting only to AMEC.

This specification provides the requirements for the hot isostatic pressing (HIP) densification through a simultaneous application of heat and pressure.

This will be an AMS 4 digit replacement for AMS-H-6875.

Ballot of AMS2801 to AMEC members only.

This is a temporary project for the purposes of balloting AMS2769 to AMEC only.

This ARP addresses the general procedure for the best practices for minimizing uncertainty when calibrating thermal conductivity and cold cathode vacuum gauges, which includes the vacuum sensor(s) and accompanying electronics necessary for a pressure measurement to be made. It also includes the best practices for an in process verification where limitations make it impossible to follow the best practices for minimizing uncertainty.

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.

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.

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.
