Ti-8Al-1Mo-1V is a near-alpha titanium alloy with moderate strength and excellent creep resistance, designed for elevated-temperature applications in jet engines and gas turbines. Duplex Annealed condition provides balanced strength and ductility through dual-phase heat treatment, yielding tensile strengths in the 140–160 ksi range with good elongation for damage-tolerant design in aircraft powerplant components operating to approximately 600°C.
