This specification covers the requirements for a hard anodic coating on magnesium alloys.
This specification covers an aircraft-quality, low-alloy steel in the form of sheet, strip, and plate.
This specification covers an aircraft quality, low alloy steel in the form of sheet, strip, and plate.
This specification covers an aircraft-quality, low-alloy steel in the form of sheet, strip, and plate.
This specification covers a corrosion and heat-resistant nickel alloy in the form of sheet, strip, and plate up to 1.000 inch (25.40 mm) in nominal thickness (see 8.7).
This specification covers a corrosion and heat-resistant steel in the form of bars, forgings, and forging stock. These products have been used typically for parts requiring oxidation resistance and high strength up to 800 °F (427 °C) and where such parts may require welding during fabrication, but usage is not limited to such applications.
This specification covers a dilute aluminum/TiB2 metal matrix composite in the form of investment castings.
This specification covers an aluminum alloy in the form of centrifugal castings.
This specification covers the requirements for producing a continuous white layer with controlled extent of porosity by means of a gaseous process, automatically controlled to maintain set values of the nitriding and carburizing potentials that determine properties of the nitrocarburized surface. Automatic control is intended to ensure repeatability of nitrogen and carbon content of the white layer which influences properties such as wear and corrosion resistance, ductility and fatigue strength.
This specification, in conjunction with the general requirements for steel heat treatment covered in AMS2759, establishes the requirements and procedures for three classes of gas, vacuum, liquid, and low pressure (LPC) carburizing and related heat treatment of parts fabricated from carburizing grade steels. Parts made from steels other than those specified in the detail specifications may be heat treated in accordance with the applicable requirements using processing temperatures, times, and other parameters recommended by the material producer unless otherwise specified by the purchaser. This specification does not cover pack carburizing.

Quenching is a heat treatment process for the rapid cooling of a metallic workpiece in water, oil, or air to obtain certain desired material properties. It is the most critical step in the sequence of heat-treating operations to preserve the solid solution formed at the solution heat-treating temperature by rapidly cooling to near room temperature. Because of the complex interaction between temperature, phase-transformation, and stress/strain relation that depends on the temperature distribution and the microstructure of the workpiece, there is no performance-informed quenching process that can be applied reliably to reduce the high scrap rate of airframe aluminum forging parts with a significant amount of residual stress and distortion. Since large aluminum forging parts are increasingly used in aerospace structures to enable structural unitization, it is important to construct a digital twin modeling approach to mirror the physical quenching process for minimizing scrap rate
