| 摘 要： | 对３０４Ｌ和３１６Ｌ奥氏体不锈钢试样在充氢后和充氢同时进行Ｘ射线衍射分析，观察到在充氢过程中存在奥氏体晶格膨胀－收缩－膨胀的现象；在充氢后时效一段时间的情况下，存在奥氏体晶格收缩－膨胀－收缩的现象，并初步讨论了可能的原因。

| Abstract: | Distortion in the crystal lattice of 304L and 316L austenitic stainless steels resulted from charging hydrogen is researched by means of X-ray diffractometer.Austenitic lattice expansion-contraction-expansion caused by charging hydrogen is found and its possible mechanisms are discussed. |
