摘要：
It has been a challenge to detect the real-time distribution of hydrogen at the micro-level. In this study, a scanning Kelvin probe force microscopy (SKPFM) was employed to characterize the surface potential changes induced by hydrogen. Variations of the surface potential were used to assess (a) the real-time distribution of hydrogen, (b) hydrogen enrichment in reverted austenite and (c) hydrogen enrichment around the crack tip induced by the stress concentration.
