利用扫描电子束辐照解吸氢离子的二维图谱，可视化了金属表面的氢渗透。所用样品为含马氏体位错的不锈钢；样品厚度为100pm，与晶粒尺寸基本一致。将样品的一侧暴露在氘气体中，并依次显示另一侧氘渗透部位。在二次电子图像中观察到的渗透位点图案与晶粒结构之间有很好的相关性。(C) 2017由Elsevier Ltd代表Acta Materialia Inc出版。
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 pm thick, which is nearly the same as the grain size. One side of the sample was exposed to deuterium gas, and sites of deuterium permeation on the other side were visualized sequentially. There was a good correlation between the patterns of the permeation sites and the grain structure observed in secondary electron images.
