The precipitation of γ-deuterides (hydrides) in titanium

Reads0

TLDR
In this paper, the crystal structure of titanium deutende precipitates on prism habit planes, and near-basal habit planes {2027}, about 27.5° from the basal plane, which can be related to dislocation mechanisms for the formation of γ by a martensitic transformation.

Hydrogen embrittlement of α titanium: In situ tem studies

TL;DR: In this paper, the effect of hydrogen on fracture in the h.c.p. α Ti-4 wt % Al alloy and the role of titanium hydride in the fracture process have been studied by deforming samples in situ in a highvoltage electron microscope equipped with an environmental cell.

The hydrogen embrittlement of titanium-based alloys

TL;DR: In this article, the authors address the hydrogen embrittlement of titanium-based alloys, including the solubility of hydrogen in α and β phases of titanium and hydride formation.
Journal ArticleDOI

Crystallographic and mechanistic aspects of growth by shear and by diffusional processes

TL;DR: In this paper, a detailed review of growth by shear and diffusional processes, both taking place predominantly by means of ledge mechanisms, are reviewed for the purpose of distinguishing critically between them at the atomic, microscopic and macroscopic levels.
Journal ArticleDOI

Hydrogen-Assisted Degradation of Titanium Based Alloys

TL;DR: An overview of hydrogen interactions with titanium alloys, with specific emphasis on the role of microstructure on hydrogen-assisted degradation in these alloys is presented in this paper, where the authors also present an analysis of the properties of different phases of the titanium lattice and the susceptibility of each phase to various forms of and conditions of hydrogen degradation.

Hydride precipitation in titanium

TL;DR: The crystal structure and morphology of hydride (deuteride) precipitates were investigated in this paper, where the deuteride was found to have a face-centered tetragonal structure (c/a = 1.09) with an ordered arrangement of hydrogen.

The precipitation of zirconium hydride in zirconium and zircaloy-2

TL;DR: In this paper, a martensitic mechanism is proposed for the formation of twinned hydride and twinned and untwinned γ-hydrides, and its implications for the precipitation behaviour of hydrides in the can of a reactor fuel element are outlined.

Thermocrystallography of higher hydrides of titanium and zirconium

H. L. Yakel
TL;DR: In this paper, the authors have shown that the second-order transformation of ZrH/sub 1.92/ is temperature-dependent and that the critical temperature of the secondorder transformation in Zrh/sub 2/2/ is unattainable in the present diffraction apparatus owing to dissociation of the hydride.

The precipitation of γ-hydride plates in zirconium

TL;DR: In this article, the authors considered the possibility that hydrides form by a displacive or shear transformation and determined the habit planes and orientation relationships of hydride alloys.
