## Description

- description: This study aims to clarify the different boundary deformation mechanisms
    between medium-carbon lath martensite and high-carbon martensitic steels. In medium-carbon
    martensite, boundary deformation can trigger the activation of minor slips in
    surrounding blocks, leading to local strain partitioning. Compared with normal
    intra-block slips along in-lath-plane slip systems, these boundary-induced minor
    slips occur on planes aligned with the deformed boundaries. On the other hand,
    boundary deformation in high-carbon martensite is strictly confined along the
    boundaries, forming intense single-peak strain concentration bands. When the high-carbon
    martensite is tempered at 500°C, the boundary-induced minor deformation bands
    are observed again. This indicates that the activation of boundary-induced minor
    deformation primarily depends on the local critical resolve shear stress (CRSS)
    around the boundaries, instead of the carbon-induce microstructure variation.
    When primary boundary deformation occurs, high CRSS impedes the activation of
    surrounding minor deformation, leading to strain concentration along the boundaries.
    With low CRSS, minor deformation can be activated near the primary boundaries,
    leading to strain partitioning effect and improved overall ductility.
