## Description

- description: In the present study, several parameters related to crack morphology
    in the case of hydrogen embrittlement were estimated by X-ray computed tomography
    and correlated with the macroscopic mechanical responses (J-integral and tearing
    modulus) obtained from the fracture mechanics tests. Even when the hydrogen content
    was high up to 4.00 wt ppm, unstable premature fracture did not immediately occur,
    and a certain crack-growth resistance could be confirmed. The three-dimensional
    crack morphology was not continuous with the formation of un-cracked ligaments
    in the uncharged specimen. In contrast, the hydrogen-related intergranular crack
    propagated more continuously with a smaller crack opening-displacement. The J-integral
    value monotonically increased with increasing estimated values of the surface
    area divided by the projected surface area on the macroscopic crack plane, indicating
    that crack meandering and branching increased the fracture energy. We defined
    crack-propagated thickness (standard deviation of the crack surface area at each
    section (parallel to the macroscopic crack plane) divided by the crack surface
    area) as a parameter representing crack meandering. The tearing modulus increased
    as the crack-propagated thickness increased, suggesting that crack meandering
    also increased the crack-growth resistance.
