Comparison with Other Standards
AMS 4928: This covers Ti-6Al-4V in bar, forging, and ring forms.
AMS 6931: Specifies beta-annealed Ti-6Al-4V with enhanced fracture toughness.
ASTM Standards: Less stringent than AMS, which prioritizes aerospace-critical properties.
Processing and Heat Treatment
Annealed Condition: AMS 4911 Ti-6Al-4V sheet typically specifies material supplied in the annealed state to relieve stresses and enhance ductility.
Fabrication: Guidelines for welding (e.g., inert gas shielding), machining, and forming to prevent contamination or embrittlement.
Application
Aerospace: Fuselage panels, wing components, engine parts (e.g., fan blades, compressor discs), and fasteners.
Other Industries: While AMS 4911 is aerospace-focused, Ti-6Al-4V is also used in the marine, chemical, and medical sectors (under different standards).
