钛及钛合金的氢渗过程研究

Study on Hydrogen Permeation Process in Titanium and Ti Alloys

摘要:

氢在钛中的扩散渗透进程分为3种模式，一是渗入钛基体中的氢与钛氢化合物自身分解的氢在氢压的推动作用下在钛基体内扩散；二是氢被位错所携带一同运动而进行扩散；三是形成的钛氢化合物的生成和迁移。

Abstract:

The processes of permeation and diffusion of hydrogen in Ti and Ti alloys can be described into three styles: the hydrogen permeating into Ti matrix and dissolved from and titanium hydride diffuses into Ti matrix under a hydrogen pressure; the hydride diffuses with the dislocation movement; and the titanium hydride forms and moves.
