用纳米力学探针研究了氢对316不锈钢单晶纳米压痕蠕变的影响。结果表明，当可扩散氢浓度C09.710-6后, 原子氢能使室温饱和蠕变位移升高近一倍。室温除气后, 其蠕变曲线和充氢前的曲线基本一致。这种可逆性表明, 氢促进蠕变是由扩散氢引起的。当C050.410-6后, 在室温时效过程中会形成'马氏体和微裂纹, '马氏体的饱和蠕变量比奥氏体要小。当C0＝174.410-6时, 充氢过程中就出现'马氏体，+'复相组织的氢致蠕变位移升高明显比单相要小。
The effect of hydrogen on nanoindentation creep of type 316 stainless steel has been investigated by nanoindentation techniques. The results showed that the crept saturation displacement increased twice After outgassing at room temperature for 200 h, the creep curves are basically identical with that before charging. This indicates the creep is caused by diffused hydrogen.
