Using the dictionary approach to Electron Backscatter Diffraction (EBSD) analysis, we address: (1) phase differentiation in highly-deformed or fine-grained materials; and (2) phase differentiation between phases with the same Bravais lattice and diff

Two approaches are proposed for the refinement of electron diffraction pattern indexing. The approaches require two basic ingredients: an accurate physics-based forward model and an algorithm to search the local orientation neighborhood. Forward mode

This paper applies the three-dimensional visualization techniques explored theoretically by Callahan, Echlin, Pollock, Singh & De Graef [J. Appl. Cryst.(2017),50, 430–440] to a series of experimentally acquired texture data sets, namely a sharp cub

Combinatorial substrate epitaxy (CSE) is used to investigate polymorph competition between metastable scrutinyite (α-PbO2) structured (s-) and stable rutile structured (r-) SnO2 during local epitaxial growth across orientation space on polycrystalli

In martensitic/bainitic bearing steels, non-observable critical cracks can initiate at inner inclusions well below the endurance limit (at 107 cycles), leading to very high cycle fatigue failure. The stability of these cracks is not ensured even if t

This work investigates the origin of creep dislocations in a Ni-base, single crystal superalloy subject to creep at an intermediate stress and temperature. Employing high angular resolution electron backscatter diffraction (HR-EBSD), electron channel

In an electron backscatter diffraction pattern (EBSP), the angular distribution of backscattered electrons (BSEs) depends on their energy. Monte Carlo modeling of their depth and energy distributions suggests that the highest energy BSEs are more lik

The fidelity – that is, the error, precision and accuracy – of the crystallographic orientations and disorientations obtained by the classical two-dimensional Hough-transform-based analysis of electron backscatter diffraction patterns (EBSPs) is

Serial sectioning and electron backscatter diffraction were used to image the three-dimensional microstructures of Mg alloy AZ31B deformed in tension and compression along sample directions that promote twinning. These measurements were used to stati
