The effect of microstructure on hydrogen diffusion in carbon steels was discussed. The weldable carbon steels, obtained by hot rolling, present a microstructural anisotropy connected with the hot plastic deformation. It was shown that Scanning Photoelectrochemical Microscope Technique (SPEM) resulted a good method to evidence the effect of the steels' microstructure on the hydrogen diffusion.

Abstract
The effect of microstructure on hydrogen diffusion in carbon steels was discussed. The weldable carbon steels, obtained by hot rolling, present a microstructural anisotropy connected with the hot plastic deformation. It was shown that Scanning Photoelectrochemical Microscope Technique (SPEM) resulted a good method to evidence the effect of the steels' microstructure on the hydrogen diffusion.File allegato/i alla scheda:
