TB6 Titanium Alloy: A New Star Of High-Strength And High-Toughness Aviation Materials 


1. Introduction To TB6 Titanium Alloy 

TB6 titanium alloy, also known as the American grade Ti-1023, is a high-strength and high-toughness near-β titanium alloy with excellent performance developed in the United States in the 1970s. Its nominal composition is Ti-10V-2Al-3Fe, and the aluminum equivalent and molybdenum equivalent are 4.0 and 11.1. This high molybdenum equivalent significantly enhances the heat treatment strengthening ability of the alloy. 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.

3. Alloy Properties of TB6 #Titanium Alloy 

The density is 4.62g/cm3, the elastic modulus at room temperature is 104GPa, the phase transition temperature is 800℃±15℃, and the hardness is 335~375HB.TB6 titanium alloy is known for its high specific strength, excellent fracture toughness, low forging temperature and strong stress corrosion resistance. These characteristics make TB6 titanium alloy have significant advantages 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 is used in the solution aging state, and the maximum hardenable cross-section is as high as 125mm. 

4, The Use of TB6 #Titanium Alloy 

The main semi-finished forms of TB6 titanium alloy include bars and forgings, and can also be made into thick plates and profiles.Due to its excellent performance, 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, Phantom 2000 and so on.In addition, TB6 titanium alloy is also widely used in the new Boeing 777 airliner and super lynx multi-purpose helicopter, which has made an important contribution to the development of the aviation industry.
