通过高分辨电子显微术（ＨＲＴＥＭ）研究了Ｔｉ－２１．７％（原子分数）Ｈ合金中γ氢化物与α－Ｔｉ基体之间的界面结构．取向关系为＜２ ０＞α／／＜１１０＞γ，｛０ １ ０｝α／／｛１ ０｝γ的α／γ界面从［０００１］α，［２ ０］α和［２ ３］α．三个方向进行观察．结果表明：（０ １ ０）α／（１ ０）。界面保持共格关系，并且发现γ氢化物的长大是通过α／γ界面上的台阶的形成和侧向扩展而进行的．
The interfacial structure of γ-hydride and α-Ti matrix in Ti-21.7% (atomic fraction) H alloy was studied by high resolution electron microscopy (HRTEM). The orientation relationship is α α / γ <110> γ, and the α / γ interface of {0 1 0} α // {1 0} γ is changed from [0001] α, [2 0] α and [2 3] . Three directions to observe. The results show that: (0 1 0) α / (1 0). The interface maintains a coherent relationship and it has been found that the growth of gamma hydride occurs through the formation and lateral expansion of the steps on the alpha / gamma interface.
