Dislocation densities have been determined and hydrogen traps have been characterized in an API 5LX60 steel. The steel has been subjected to different degrees of plastic strain (ɛP) by cold rolling. The dislocation densities has been determined by the analysis of the peak broadening on X-Ray diffractograms. The traps have been characterized through the measurement of hydrogen permeation transients and fitting of a trapping model to the experimental data. The relationship between hydrogen traps and dislocation density is discussed.
