| 摘 要： | 本文研究了铁中氢与辐照缺陷的相互作用。氢与这些缺陷结合,形成不同类型的氢与缺陷的复合体,在从低温到高温的时效过程中,可以清楚地观察到间隙型位错环(>300℃)、空位型位错环(>450℃)和空洞(520℃)的形成。研究表明,这三种缺陷分别是氢与间隙原子、氢与单个空位、氢与复数个空位等三种复合体聚集而成。

| Abstract: | The interaction between hydrogen and irradiated defects in iron was studied. Different kinds of complexes of hydrogen and defects would form if hydrogen was trapped by the defects. During aging at various temperatures, it was observed that interstitial-type loops formed above 300℃, vacancy-type loops formed above 450℃ and voids formed at 520℃. We consider that such complexes as H-I or H-Is, H-V and H-Vs result in interstitial-type loop, vacancy-type loop and void, respectively. |
