Query: Temperature increases and thermoplastic microstructural evolution in
  adiabatic shear bands in a high-strength and high-toughness 10 wt.% Ni steel   A 10 wt.% nickel-steel has been developed for high pressures and
low-temperature applications, due to its high strength, excellent toughness,
and low ductile-to-brittle transition temperature (DBTT). Under dynamic loading
conditions this steel is, however, prone to shear localization that manifests
as adiabatic shear bands (ASBs). The temperature increases and thermoplastic
microstructural evolution in the ASB are studied in detail, from the
macroscopic length scale to the atomic-scale employing correlative
electron-backscatter diffraction (EBSD), transmission electron microscopy
(TEM), and atom-probe tomography (APT). From a calculation of the temperature
increase under adiabatic conditions, based on the conversion of plastic-work to
heat generation, the microstructural transitions in the ASB are discussed
specifically for: (i) a b.c.c.-f.c.c. phase-transformation and their elemental
partitioning; (ii) the thermodynamic model for the compositional change of the
V(Nb)-rich carbonitride precipitates during a temperature increase; and (iii)
grain-refinement and rotation by dynamic/mechanical recrystallization
processes. Solute segregation at subgrain boundaries, measured using the
Gibbsian interfacial excess methodology, reveals how solute segregation
contributes to the instability of localized shear-deformation by promoting the
depinning of solute elements and the migration of a grain boundary. Finally, a
kinetic model for grain refinement/rotation within an ASB is described by the
dynamic recrystallization behavior with: (i) subgrain formation; (ii)
rotation/refinement by deformation; and (iii) grain growth by subgrain
coalescence with further rotation and a temperature increase. The temperature
increase under dynamic deformation in an ASB promotes grain boundary migration
and subgrain coalescence to create a large degree of equiaxed grains with a low
density of imperfections.
