Residual Stress Measurement and Classification, Metallic Structural Alloy Products and Finished Parts

2023-05-22
AS7045
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. These stresses may exist within a single element, or they may be the result of a joining process. Such quantification and classification may be required when residual stresses within mill stock or 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 (especially strength, durability, and fracture performance).

Carburizing and Heat Treatment of Carburizing Grade Steel Parts

2021-09-15
AMS2759/7E
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.

Vacuum Investment Cast PH13-8Mo Corrosion Resistant Steel

2020-06-01
AIR4394A
An industry-wide interest has arisen with regards to the properties and capabilities of investment cast PH 13-8Mo corrosion resistant steel. Specifically of interest are the structural applications in the aerospace industry for this product heat treated to the H1000 condition. The objective of this AMEC cooperative test program was to generate and compile useful data for aerospace structural evaluation of investment cast PH 13-8Mo heat treated to H1000. The focus of the test program was the determination of overall mechanical properties, fatigue, fracture toughness, and crack growth data along with basic microstructural evaluation of the investment cast material. Additional objectives included the evaluation of mechanical property variations between cast and machined tensile specimens and evaluation of microstructural constituents. All testing was performed to determine the suitability of PH 13-8Mo, H1000 investment castings for use in the aerospace industry.
