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

TL;DR: The results suggest that the measured lower bound GND density noise floor broadly agrees with Wilkinson and Randman's 2009 prediction, where a decrease in step size or an increase in misorientation uncertainty increases the noise floor.
Journal ArticleDOI

Evolution of dislocation density distributions in copper during tensile deformation

TL;DR: In this paper, the evolution of dislocation storage in deformed copper was studied with cross-correlation-based high-resolution electron backscatter diffraction, and the average dislocation density increases with imposed macroscopic strain in accord with Ashby's theory of work hardening.
Journal ArticleDOI

Tutorial: Crystal orientations and EBSD — Or which way is up?

TL;DR: In this paper, a series of conventions used to describe crystal orientations and coordinate systems are outlined, which can be used to successfully demonstrate that a consistent frame of reference is used in the sample, unit cell, pole figure and diffraction pattern frames of reference.
Journal ArticleDOI

Is stored energy density the primary meso-scale mechanistic driver for fatigue crack nucleation?

TL;DR: In this paper, the authors investigated fatigue crack nucleation in a powder metallurgy produced nickel alloy containing a non-metallic inclusion and found that local slip accumulation was a necessary condition for crack formation and that in addition, local stress and density of geometrically necessary dislocations are involved.
Journal ArticleDOI

Broadband plasmon induced transparency in terahertz metamaterials.

TL;DR: This work presents the simulation, implementation, and measurement of a broadband PIT metamaterial functioning in the terahertz regime, and finds a broad transparency window across a frequency range greater than 0.40 THz is obtained.
