Adiabatic temperature increase associated with deformation twinning and dislocation plasticity

Coupling of Electron Channeling with EBSD: Toward the Quantitative Characterization of Deformation Structures in the SEM

“…[35][36][37][38]40 It has been also proved as a valuable technique to measure dislocation densities. [41][42][43] Figure 3 illustrates several application examples of the ECCI technique (details can be found in Refs. 40,41,43).…”

“…33 Due to the high spatial resolution of EBSD (35 ± 5 nm 34 ), crystal defects can be imaged in submicrometer areas of deformed bulk materials. In the last few years, we have applied the EBSD-based ECCI approach to several cases, namely, the characterization of complex deformation structures such as dislocation and nano-twin substructures in bulk deformed high-Mn TWIP steels (TWIP: twinning induced plasticity), [35][36][37][38][39] the investigation of dislocation patterns, 36,37,40 the measurement of dislocation densities in deformed alloys, 41,42 and the characterization of individual dislocations and stacking faults. 43,44 These studies have demonstrated the feasibility of the EBSD-based ECCI approach on the quantitative characterization of complex deformation structures in bulk materials.…”

Infrared thermography coupled with digital image correlation in studying plastic deformation on the mesoscale level

“…They show particular values in characterizing the heterogeneous deformation process of materials, which can be embodied both in the thermal and kinematic fields [38][39][40][41]. Presently, a noteworthy tendency of the current research is the transformation of the observation scale from the conventional macroscale to the mesoscale and even microscale.…”

Quantitative infrared thermography applied to subgrain scale and the effect of out-of-plane deformation

“…In the field of experimental solid mechanics, infrared thermography is found particularly useful in evaluating the energy dissipation of deforming materials, which is usually a very sensitive indicator of the microstructural changes [12][13][14]. The assessment of the dissipated energy is crucial for establishing an experimental energy balance in a plastic deformation.…”
