Effect of Texture on Hydrogen Permeability in Low Carbon Al-Killed Steels

Abstract:

The susceptibility to fish-scale formation of cold rolled Al-killed low carbon enamel grade steel sheets is mainly determined by the hydrogen permeability. The role of the grain orientation in the hydrogen permeation time was investigated using scanning electron microscope based electron backscatter diffraction measurements. The fragmentations of massive cementite phase have a significant influence not only on the hydrogen permeability but also on the evolution of texture during the cold rolling process. Results showed that {111}[uvw] texture act as trapping site for hydrogen.
