Grain-scale Stress and GND Density Distributions around Slip Traces and Phase Boundaries in a Titanium Alloy

Journal Wuhan University of Technology, Materials Science Edition, 2018
For TA15 titanium alloy, slip is the dominant plastic deformation mechanism because of relatively high Al content. In order to reveal the grain-scale stress field and geometrically necessary dislocation (GND) density distribution around the slip traces and phase boundaries where the slip lines are blocked due to Burgers orientation relationship (OR ...

EFFECT OF LOCAL STRAIN AND GND DENSITY ON CRACK INITIATION IN ALLOY 600.

, 2019
In this work, strain and geometric necessary dislocation (GNDs) have been measured around various grain boundaries after subjected to a 4-point bend test in simulated PWR primary water conditions, with the aim of clarifying which local conditions trigger SCC initiation.

The dislocation behaviour and GND development in a nickel based superalloy during creep [PDF]

International Journal of Plasticity, 2019
In the current study, dislocation activity and storage during creep deformation in a nickel based superalloy (Waspaloy) were investigated, focussing on the storage of geometrically necessary (GND) and statistically stored (SSD) dislocations.

Geometrically necessary dislocation density distributions in Ti–6Al–4V deformed in tension

Acta Materialia, 2011
We have used cross-correlation-based analysis of electron backscatter diffraction patterns to map lattice rotations in polycrystalline samples of Ti-6Al-4V before and after moderate (6%) tensile deformation.

Measurement of geometrically necessary dislocation density with high resolution electron backscatter diffraction: Effects of detector binning and step size

Ultramicroscopy, 2013
Recent advances using cross-correlation analysis of full resolution high quality electron backscatter diffraction (EBSD) patterns have provided a method for quantitatively mapping the stored dislocation density at high spatial resolution.
