2018925 · Alloy 834 (Ti-5.8Al-4Sn-3.5Zr-0.7Nb-0.5Mo-0.35Si-0.06C), a relatively rece nt grade, in contrast is used in D + E condition, with a 5-15% equiaxed D in the microstructure to optimize both creep and fatigue strength (Gogia, 2005). The alloy was aimed at replacing the Alloys 685 and 829 preferred in European jet engines.
Titanium IMI 829 (Ti-5.5Al-3.5Sn-3Zr-1Nb-0.25Mo-0.3Si), Heat treatment: Beta heat treated at 1050 °C, Air Cooled and aged 2 hours at 625 °C Characteristics: Near-alpha alloy, medium strength, good high temperature properties, high creep
829 (Ti-5.5Al-3.5Sn-3Zr-1Nb-0.25Mo-0.3Si) Titanium Alloy, Weldable, High Strength, High Temperature, Creep Resistant Alloy IMETAL 829 combines creep resistance up to 540°C with good oxidation resistance. It is weldable and like TIMETAL 685, TIMETAL
