TL;DR: In this paper, the orientation-dependent stored energy of deformed grains from the data measured using electron back-scattered diffraction (EBSD) analysis was evaluated using a subgrain method.
Abstract: This study has been conducted to evaluate the orientation-dependent stored energy of deformed grains from the data measured using electron back-scattered diffraction (EBSD) analysis. The stored energy in deformed grains is an important term as a driving force for static recrystallization of cold-rolled steels. Subgrain method based on subgrain structure is used for quantitative analysis of the stored energy developed in cold-rolled low carbon steels to a reduction of 50% and compared with conventional methods. The result demonstrated that the main texture components having high stored energy are mainly of {5 5 4}〈2 2 5〉 orientation and partially γ-fibre orientations. The subgrain method appears to be a proper method to evaluate the spatial distribution of stored energy as a function of orientation.

TL;DR: In this article, the microstructural characterization of induced adiabatic shear bands (ASB) in a hot-rolled interstitial free (IF) steel deformed at high strain rates (>2.8 × 104 s−1) under controlled conditions at −50 and 25°C.
Abstract: We report the microstructural characterization of induced adiabatic shear bands (ASB) in a hot-rolled interstitial free (IF) steel deformed at high strain rates (>2.8 × 104 s−1) in a split Hopkinson bar under controlled conditions at −50 and 25 °C. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and electron backscatter diffraction (EBSD) were used to reveal the degree of subdivision within ASB and neighboring grains. Deformation twins were found in adjacent grains suggesting that twinning occurs before the flow associated to shear banding. Progressive subgrain misorientation (PriSM) recrystallization is a plausible mechanism to explain the development of a new structure consisting of weakly textured ultrafine grains (0.1–0.5 μm) within the ASB. Recrystallization is proposed to occur by the formation and mechanical rotation of subgrains during deformation, coupled with boundary refinement via diffusion during shear band cooling. The presence of elongated subgrains and grains perfectly aligned within regions resembling a former lamellar structure within bands supports the occurrence of such a mechanism.
