abstract = {The formation of Mn–C short-range ordering (SRO) has a
great influence on the mechanical properties of high-Mn
steels. In the present work, the formation of Mn–C SRO
during recrystallization of an X60Mn18 steel was
investigated by means of a combined study employing small
angle neutron scattering (SANS) and ab initio ground-state
energy calculations based on density-functional theory. The
SANS measurements prove the presence of Mn–C SRO in the
recrystallization annealed X60Mn18 steel and indicate the
evolution of the SRO during recrystallization. The results
show that with the increase in annealing time, the mean size
of the Mn–C SRO decreases, whereas the number density
increases. The ab initio calculations well describe the
energetically favored condition of Mn–C SRO and provide
the theoretical explanation of the clustering formation and
evolution in the X60Mn18 steel. The stress-strain curve of
the X60Mn18 steel exhibits a high strain-hardening rate and
the plastic deformation is characterized with a series of
serrations during a uniaxial tensile test. In the end, the
correlation between Mn–C SRO and the serrated flow of
high-Mn steels is further discussed.},
