The role of hydrogen in the interstitial elements of titanium and titanium bar

Titanium and titanium alloys in the interstitial elements mainly of hydrogen , nitrogen , carbon, boron and hydrogen and silicon. Their impact on the titanium and titanium alloys have poor . Described herein will focus on the role of hydrogen, oxygen , nitrogen ,titanium whole distributor carbon and boron.
The role of hydrogen in titanium and titanium alloys . In an industrial atmosphere , the maximum solid solubility of hydrogen in the β titanium is about 2.0% (49 atomic% ) . A titanium hydrogen of about 0.18% maximum solid (7.8 atomic% ) , in 319 ℃. This occurs at temperatures below the eutectoid transformation , its eutectoid point of approximately 1.62% ( 44% atom ) . β = a + γ
Eutectoid temperature of 281 ℃, hydrogen in the case of titanium the maximum solid solubility of a 0.13% (6.3 atomic% ) . γ phase is TiH2 compound having the face-centered cubic lattice , a = 4.44 Å . When the temperature dropped to a low 125 ℃, the solubility of hydrogen in a sharp decline titanium , about 0.001 to 0.0029% ( 0.05 to 0.14 atomic% ) . Should index, temperature and pressure in a hydrogen solubility in titanium and titanium- β by the solubility . Titanium and hydrogen interactions are reversible.

Hydrogen in titanium and titanium alloys in
Titanium and titanium alloys can cause hydrogen embrittlement various sources , causing low stress brittle fracture , therefore, can be used to prepare titanium and titanium alloy powder. Its approach is to titanium and titanium alloy materials ( such as chips , scrap , etc. ) in the 300 ~ 400 ℃ hydride embrittlement in a hydrogen atmosphere medical titanium plates, broken glass is made by milling the powder .
