## Description

- description: "Mechanism of dynamic strain aging (DSA) effect in high-Mn austenitic
    steel, and its correlation with the Portevin-Le Chatelier (PLC) bands, was elucidated
    using in-situ synchrotron XRD measurement and digital image correlation (DIC)
    method during a tensile test. The average dislocation velocity beyond the front
    of the PLC band ranged from 10-2 to 10-1 nm/s but reached the order of 100 nm/s
    within the front of the PLC band. In comparison, carbon diffusivity was significantly
    lower, allowing carbon to diffuse only from 10-7 to10-9 nm in one second. The
    findings indicate that dislocations beyond the front of the PLC band were pinned
    by nearby carbon atoms, while dislocations within the front of the PLC band became
    de-pinned from the\r\ncarbons. Such localized pinning and de-pinning of dislocations
    occurred sequentially during deformation, appearing as the propagation of PLC
    bands in macroscopic scale. "
