Zusammenfassung:This research presents some of the very new aspects concerning microscopic hydrogen diffusion for thermally treated samples: normalized, heated and overheated specimens. In addition, this article presents comparisons between microscopic diffusible hydrogen quantities for grain bodies and for space between grains, for the all three analyzed samples. In the final part of the paper, the authors present the conclusions regarding the hydrogen diffusion process, at a microscopic level, corresponding to heat treatments for the S235JR (SREN 10027-1) sample.
