I. Introduction of TB6 titanium alloy
TB6 titanium alloy, also known as U.S. grade Ti-1023, is a high-strength, high-toughness, near-beta-type titanium alloy developed in the United States in the 1970s with excellent properties. Its nominal composition is Ti-10V-2Al-3Fe, with an aluminum equivalent (AI) and molybdenum equivalent (MOE) of 4.0 and 11.1, respectively. This high MOE significantly enhances the alloy's heat-treatable strengthening capability. In addition, a small amount of AI not only strengthens the α-phase, but also inhibits the formation of the ω-phase during quenching and aging.
Second, TB6 titanium alloy alloy properties
Density 4.62g/cm³, room temperature modulus of elasticity 104GPa, phase transition temperature 800 ℃ ± 15 ℃, hardness 335 ~ 375HB. TB6 titanium alloy is known for its high specific strength, excellent fracture toughness, low forging temperature and strong resistance to stress corrosion. These properties give TB6 titanium alloy a significant advantage in the manufacture of high-strength titanium forgings. Through heat treatment, TB6 titanium alloy can achieve an ideal match of strength, plasticity and toughness over a wide range. In addition, the alloy can be used in the solid solution aging state with a maximum hardened cross section of up to 125mm.



Third, the use of TB6 titanium alloy
The main semi-finished forms of TB6 titanium alloy include bars and forgings, which can also be made into thick plates and profiles. Due to its excellent properties, TB6 titanium alloy is particularly suitable for the manufacture of isothermal die forgings and hot die forgings. In fact, TB6 alloy has been widely used in a variety of civil and military aircraft, such as Boeing 757, A320, B-1B, Mirage 2000 and so on. In addition, TB6 titanium alloy is also used in large quantities in the new Boeing 777 airliner and the Super Bobcat multi-purpose helicopter, which has made important contributions to the development of the aviation industry.
