Preferred orientation of hydroxylapatite in the scales and fins of seawater Lateolabrax japonicus determined using XRD pole figures and ODF

open access: yes工程科学学报, 2017
Pole figures measured using X-ray diffractometry were used to analyze the orientation of crystalline hydroxylapatite (HAP) in the scales and fins of seawater Lateolabrax japonicus.

Reconstruction of incomplete X-ray diffraction pole figures of oligocrystalline materials using deep learning

open access: yesScientific Reports, 2023
X-ray diffraction crystallography allows non-destructive examination of crystal structures. Furthermore, it has low requirements regarding surface preparation, especially compared to electron backscatter diffraction. However, up to now, X-ray diffraction

Generalized pole figures from post-processing whole Debye–Scherrer patterns for microstructural analysis on deformed materials

open access: yesJournal of Synchrotron Radiation, 2022
Debye–Scherrer patterns, obtained from X-ray diffraction experiments using synchrotron light in transmission geometry, were analysed to construct generalized pole figures, and further used as input for an orientation distribution function inversion ...

Design and trade-offs of a pole-sitter mission [PDF]

open access: yes, 2013
This paper provides a mission analysis and systems design of a pole-sitter mission, i.e. a spacecraft that is continuously above an Earth Pole, and can provide real-time, continuous and hemispherical coverage of the polar regions.

Comparison of Ultrasonic Pole Figures Based upon Ultrasonic Nondestructive Evaluation Method with Pole Figures Based upon Finite Element Polycrystal Model [PDF]

open access: yes, 2003
The ultrasonic wave velocities in a polycrystalline aggregate are sensitively influenced by texture change due to plastic deformation, and their relationship was systematically analyzed by Sayers [J. Phys. D: Appl. Phys. 15 (1982)]. According to Sayers’s

3D MORPHOLOGICAL ANALYSIS OF COMPOSITE MATERIALS WITH AGGREGATES OF SPHERICAL INCLUSIONS

open access: yesImage Analysis and Stereology, 2011
Composite materials containing aggregates of spherical inclusions are studied from 3D images obtained by X-ray microtomography. Using two point statistics in different directions, and the empirical distribution of orientations of pairs of inclusions ...

Changer in the texture orientation of electrolytic nickel by cold air plasma

open access: yesЛитьë и металлургия, 2020
The effects of cold air plasma influence on the change in the microstructure, stress state and texture of the cathode nickel brand H-1 were studied. By the method of target metallography it has been established that the microstructure does not change ...

Race to the Pole: Matthew Henson, Arctic Explorer

open access: yesAmerican Studies in Scandinavia, 2022
In his memoir, A Negro Explorer at the North Pole (1912), Matthew Henson describes the toll of his and Peary’s race to the Pole. This record of the 1908-09 Arctic expedition complicates established understandings of the “Dash to the Pole” and his own ...

Improved determination of fcc/bcc orientation relationships by use of high indexed-pole figures

open access: yes, 2006
The use of variants to analyze fcc/bcc orientation relationships is demonstrated by EBSD data. Because of multiply occupied poles in the stereographic projections low indexed pole figures are not always suitable.
