Grain boundary hydride habit in Zircaloy-2
TLDR
In this paper, grain boundaries lying in certain directions relative to adjacent grains have been found to be preferred sites for zirconium hydride precipitation in Zircaloy-2, and the most favourable sites are those grain boundaries which make angles of 35°−40° and 60°−75° to the basal planes of the adjacent grains.About:

Hydrides and delayed hydrogen cracking in zirconium and its alloys
D. O. Northwood,U. Kosasih +1 more
TL;DR: A critical review of published data on hydrogen, hydrides, and delayed hydrogen cracking (or hydrogen-induced delayed cracking, HIDC) in zirconium and its alloys is presented in this paper.

Crystallography of Zirconium Hydrides in Recrystallized Zircaloy-2 Fuel Cladding by Electron Backscatter Diffraction
TL;DR: In this paper, the delta-phase Zr hydrides were examined by electron backscatter diffraction (EBSD) and the most common crystallographic relationship for both types of the hyddrides precipitated at the inter- and intra-granular sites was identical at (0001)(alpha) // {111}(delta), with {1017}(alpha) and { 111} (delta) being the occasional exception only for the intergranular radial hydride.
Journal ArticleDOI
The stress orientation of hydride in zirconium alloys
TL;DR: Li's theory of stress orientation of disc shaped precipitates is applied to the problem of stress orientations of hydride in zirconium alloys as mentioned in this paper, and the experimental observations are shown to be consistent throughout.

TL;DR: In this paper, a hydride preference index (HPI) was proposed to describe the relative preference, if any, of hydrides in Zircaloy 2 microstructures.

Microstructure and Formation Mechanisms of δ-Hydrides in Variable Grain Size Zircaloy-4 Studied by Electron Backscatter Diffraction
TL;DR: In this paper, electron backscatter diffraction (EBSD) was used to examine the structure and crystallography of δ phase hydrides in as-received fine grain and "blocky alpha" large grain Zircaloy-4.

Grain Boundaries in Metals
TL;DR: In this article, it was shown that grain boundary precipitation would vary in magnitude according to the degree of disorder existing at the boundary, and with position in the boundary between two given crystal grains if the boundary changed in direction.

The orientation of zirconium hydride on grain boundaries in zircaloy-2
TL;DR: An electron microscopic investigation on the orientation relationships between grains having hydrides in their boundaries has been carried out on Zircaloy-2 as discussed by the authors, where all other habit planes recorded by other workers were found to operate for the precipitation of zirconium hydride.
