Abstract: Hydrogen behavior of Nb-containing HSLA steel tempered at 560, 600 and 640 ℃ was investigated by means of X-ray diffraction, electrochemical hydrogen permeation and dynamic hydrogen charging tensile tests, respectively. The quantitative relations of hydrogen diffusion coefficient, hydrogen concentration, as well as activation energy for hydrogen diffusion with hydrogen trap sites density were established. The results show that with the increase of tempering temperature, the dislocation density of the tested steel decreases, hence the hydrogen trap sites density decreases. In the meantime, the hydrogen diffusion coefficient increases, while the activation energy of hydrogen diffusion and hydrogen concentration decreases, which reduces the susceptibility of hydrogen embrittlement.

Key words: Nb microalloying, X-ray diffraction, hydrogen permeation, hydrogen embrittlement susceptibility
