abstract = {The localized deformation in the high-Mn austenitic
Fe-18Mn-0.6C (wt $\%)$ steel manifests itself as serrations
in the stress–strain curves and Portevin–Le Chatelier
(PLC) bands characterized by digital image correlation (DIC)
analysis in uniaxial tensile tests. The serrated flow is
correlated with the nucleation, propagation and dying away
of PLC bands. The PLC band velocity decreases with
increasing strain. In this present study, the Mn-C
short-range ordering (SRO) was analyzed quantitatively using
small angle neutron scattering (SANS) in Fe-18Mn-0.6C steel.
The size and number density of the Mn-C SRO were determined
as a function of engineering strain at room temperature. The
mean radius of the Mn-C SRO decreases, while the number
density increases when there is an increase in the
engineering strain. The influence of PLC bands on Mn-C SRO
in tensile tests was further discussed},
