Ti-6.5Al-1Mo-1V-2Zr

Overview Of Ti-6.5Al-1Mo-1V-2Zr

Ti-6.5Al-1Mo-1V-2Zr is a near-α-type titanium alloy with high aluminum equivalent, and its nominal composition is Ti-6.5Al-2Zr-1Mo-1V. The alloy has moderate room temperature and high temperature strength, good thermal stability and welding performance, and good process plasticity, and is mostly used to manufacture aircraft structural parts or engine parts.

Because its composition contains more α-stabilizing elements AI, the solid solution strengthening of the α phase is achieved, so that the alloy has both good thermal strength and weldability, and has process plasticity close to that of α+β-type titanium alloys. In addition, Ti-6.5Al-1Mo-1V-2Zr also has good fracture toughness, fatigue limit, stress corrosion resistance and welding performance, so it is widely used in aerospace, military, chemical industry and other fields.

The working temperature of Ti-6.5Al-1Mo-1V-2Zr can reach 500℃ for a long time (3000h), and 800℃ for an instant (no more than 5min). When working at 450℃, the service life can reach 6000h. Ti-6.5Al-1Mo-1V-2Zr is mainly used to manufacture aircraft, engine parts and welded load-bearing parts that work for a long time below 500℃.
