Ti-6Al-2Sn-4Zr-2Mo is a near-alpha titanium alloy strengthened by aluminum and molybdenum additions, designed for elevated-temperature applications requiring moderate strength and creep resistance up to approximately 600°C in aerospace gas turbine engines and compressor casings. Duplex annealed condition provides optimal combination of strength and fracture toughness through controlled recrystallization and alpha-phase stabilization, with yield strengths typically 800–1000 MPa and good ductility (8–15% elongation) across bar, forging, and sheet product forms.
