## Description

- description: A typical hydrogen-related transgranular fracture, namely quasi-cleavage
    fracture, is usually accompanied by serrated markings on the resultant fracture
    surfaces in steels with body-centered cubic phases. The present paper investigated
    the microscopic three-dimensional morphology and crystallographic feature of serrated
    markings in a 2Mn-0.1C steel mainly composed of ferrite microstructure. The serrated
    markings corresponded to the corners of the step-like morphologies which consisted
    of microscopic {011} facets whose longitudinal directions were almost parallel
    to <011> or <211> direction. In addition, the microscopic {011} quasi-cleavage
    facets had the largest inclination angle from tensile axis among six crystallographically
    equivalent {011} planes, suggesting that resolved normal stress imposed on the
    {011} plane is an important factor for the hydrogen-related quasi-cleavage fracture.
    We propose that not only the slip deformation enhanced by hydrogen but also the
    coalescence of vacancies/voids induced by hydrogen-enhanced plastic deformation
    should be considered for understanding the mechanism of the hydrogen-related quasi-cleavage
    fracture along the {011} planes.
