## Description

- description: Improving hydrogen embrittlement resistance is a prerequisite for expanding
    the application of high-strength steels. A high-strength deformed pearlitic steel
    exhibits excellent hydrogen embrittlement resistance presum- ably because strong
    hydrogen trapping sites induced by deformation prevent hydrogen accumulation at
    potential crack initiation sites. This work reports the conclusive identification
    of the strong hydrogen trapping site in the deformed pearlitic steels. Thermal
    desorption spectroscopy showed a distinct hydrogen desorption peak at high temperature
    of ~ 600 K solely in the deformed pearlite. Scanning transmission electron microscopy
    and atom probe tomography analyses revealed that the deformation resulted in strain
    localization at the ferrite/cementite interfaces, together with the formation
    of a large number of dislocations, leading to the strong segregation of deuterium,
    a natural isotope of hydrogen, at the interface. Therefore, hydrogen trapping
    in the deformed pearlitic steels is attributed to the strained ferrite/cementite
    interface.
