What titanium alloys are there?

According to their influence on the phase transition temperature, they can be divided into three categories: ① The elements that stabilize the α phase and increase the phase transition temperature are α stable elements, including aluminum, carbon, oxygen and nitrogen. Among them, aluminum is the main alloying element of titanium alloy, which plays an obvious role in improving the strength of the alloy at room temperature and high temperature, reducing the specific gravity and improving the elastic modulus. ② The elements that stabilize the β phase and lower the phase transition temperature are β stable elements, which can be divided into isomorphic and * * * precipitation types. The former includes molybdenum, niobium and vanadium. The latter includes chromium, manganese, copper, iron and silicon. ③ The elements that have little influence on the phase transition temperature are neutral elements, such as zirconium and tin.
