(8) Ti-10V-2Fe-3Al alloy
Ti-10V-2Fe-3Al alloy has excellent hardenability, high strength,
and high fatigue strength. It is mainly used for landing gear (part of
the main landing gear for take-off and landing). Major relevant standards
are AMS 4983, 4984, 4986, and 4987. The yield strength of
the STA material is 1,105 MPa or higher, tensile strength is 1,240
MPa or higher, and elongation is 4% or higher at room temperature.3)
