Abstract

Hydrogen permeation from a metal surface was visualized by two-dimensional mapping of hydrogen ion desorbed by scanning electron beam irradiation. The sample used was stainless steel containing dislocations of martensite ; the sample was 100 µm thick, which is nearly the same as the grain size. There was a good correlation between the patterns of the permeation sites and the grain shape observed in secondary electron images.
