## Description

- description: Combined addition of interstitial-substitutional elements has been
    acknowledged to contribute to the increase in the strengths of steels. For further
    improvements in mechanical properties, their atomic-scale interaction mechanisms
    with dislocations are required to be examined. In this study, both high-resolution
    transmission electron microscopy and atom-probe tomography were used to correlate
    interstitial-substitutional elements with dislocation characteristics in austenitic
    stainless steels. Three types of dislocation core structures are identified and
    associated with their strain fields as well as N and Cr atoms in the N-added steels.
    It is revealed that N atoms interact elastically with the dislocations, followed
    by the segregation of Cr atoms via the chemical interaction between N and Cr atoms.
    This insight significantly improves the understanding of the multiple alloying
    mechanism in metallic materials such as interstitial alloys and high-entropy alloys.
