Overview of AMS4928 Aerospace Standard
AMS4928 Aerospace Standard
AMS4928 is one of the American aerospace material standards (Aerospace Material Specification, referred to as AMS), which mainly focuses on the technical requirements for titanium and titanium alloy materials.
AMS4928 Standard Overview
1. Material Type
Usually covers titanium and titanium alloys, such as the common Ti-6AI-4V (titanium alloy, Grade 5), which is a high-strength, lightweight material widely used in the aerospace field.
2.Main applications:
Used in aircraft structural parts, engine parts, spacecraft components and other fields that require high strength, corrosion resistance and high temperature resistance.
3.Technical requirements
Chemical composition: strictly specify the content range of alloying elements (such as aluminum and vanadium). Mechanical properties: including tensile strength, yield strength and elongation (such as the tensile strength of Ti-6AI-4V is usually ≥895 MPa). Heat treatment: may involve solid solution treatment, aging treatment and other process requirements. Non-destructive testing: such as ultrasonic testing and X-ray testing to ensure that the material has no internal defects.
4.Other requirements
Surface quality, dimensional tolerance, microstructure, etc. must meet aerospace standards
5. Commonly related standards
ASTM B348: Standard specification for titanium and titanium alloy bars, which may overlap with the material properties of AMS4928.
AMS4911: Another titanium alloy plate standard, applicable to materials with different processes or states.
MIL-T-9046: Military titanium alloy standard, some requirements are similar to aerospace standards.
