Journal ArticleDOI
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?
T.B. Britton,Jun Jiang,Yi Guo,Yi Guo,Arantxa Vilalta-Clemente,David Wallis,Lars N. Hansen,Aimo Winkelmann,Angus J. Wilkinson +8 more
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.
Zhihua Zhu,Xu Yang,Jianqiang Gu,Jun Jiang,Weisheng Yue,Zhen Tian,Masayoshi Tonouchi,Jiaguang Han,Weili Zhang,Weili Zhang +9 more
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.
