Alloying

(1) Alloying elements can be divided into three categories according to their effect on phase transition temperature:

α -stable elements, such as aluminum, carbon, oxygen and nitrogen, stabilize α phase and increase phase transition temperature. Aluminum is the main alloying element of titanium alloy, which has obvious effect on improving the strength of alloy at room temperature and high temperature, reducing the specific gravity and increasing the elastic modulus.

(2) β -stable elements can be divided into two types: isocrystalline and eutectoid. Products made of titanium alloy

The former has molybdenum, niobium, vanadium and so on; The latter has chromium, manganese, copper, iron, silicon and so on.

(3) The elements that have little effect on phase transition temperature are neutral elements, such as zirconium and tin.

Oxygen, nitrogen, carbon and hydrogen are the main impurities in titanium alloys. The solubility of oxygen and nitrogen in the α phase is greater, which has a significant strengthening effect on the titanium alloy, but decreases the plasticity. The content of oxygen and nitrogen in titanium is usually below 0.15 ~ 0.2% and 0.04 ~ 0.05%, respectively. Hydrogen has very little solubility in the α phase, and too much hydrogen dissolved in titanium alloys produces hydrides, which make the alloy brittle. Hydrogen content in titanium alloy is usually controlled below 0.015%. The dissolution of hydrogen in titanium is reversible and can be removed by vacuum annealing.
