氢对Al和V在β纯Ti中扩散的影响

EFFECT OF HYDROGEN ON THE DIFFUSION OF Al AND V IN PURE TITANTUM

本文采用扩散偶实验方法研究了氢对 Al、V 合金元素在β纯 Ti 中扩散的影响。结果表明,氢可以提高 Al,V 的扩散系数,尤其使 Al 的的扩散系数提高一个数量级。氢的这一作用被认为是氢在 Ti 中的弱键效应所致。

The effect of hydrogen on the diffusion of Al and V in pure titanium wereinvestigated by diffusion couple experiments.It was shown that hydrogen can enhance thediffusivities of both Al and V.An order of increasing the diffusivity of Al has beenobtained.These results are attributed to the decohesion effect caused by the hydrogen intitanium.
