Estimations of bulk geometrically necessary dislocation density using high resolution EBSD.
Ultramicroscopy, 2013Characterizing the content of geometrically necessary dislocations (GNDs) in crystalline materials is crucial to understanding plasticity. Electron backscatter diffraction (EBSD) effectively recovers local crystal orientation, which is used to estimate the lattice distortion, components of the Nye dislocation density tensor (α), and subsequently the ...

Crystallographic aspects of geometrically-necessary and statistically-stored dislocation density
Acta Materialia, 1999Abstract Classical plasticity has reached its limit in describing crystalline material behavior at the micron level and below. Its inability to predict size-dependent effects at this length scale has motivated the use of higher-order gradients to model material behavior at the micron level.

Abstract The present investigation examined the evolution of geometrically necessary dislocation (GND) structure following tensile deformation in a commercially produced dual phase steel, DP 590. GND measurements were made using electron back scatter diffraction (EBSD).

A dislocation density based constitutive model for face-centred cubic crystals is introduced and implemented into a crystal plasticity finite element framework. The approach assumes a homogeneous dislocation structure and tracks the dislocation evolution on each slip system.

The characterization of geometrically necessary dislocation (GND) is central to understanding the plastic deformation in materials. Currently, fast and accurate determination of GND density via Electron Backscatter Diffraction (EBSD) remains a challenge.
