Hydride embrittlement in ZIRCALOY-4 plate: Part I. Influence of microstructure on the hydride embrittlement in ZIRCALOY-4 at 20 °C and 350 °C
J. B. Bai,C. Prioul,D. François +2 more
TL;DR: In this article, a full-coverage model is proposed to estimate the critical hydrogen content that makes ZIRCALOY-4 totally brittle, and the effect of microstructure on hydride embrittlement in different metallurgical states is explained according to the modeling.

A review on hydride precipitation in zirconium alloys
TL;DR: In this paper, the authors provide a concise summary of experimental and computational studies performed on hydride precipitation in zirconium alloys since the 1960's, with specific consideration given to the phase field model, which has become a popular and powerful computational tool for modeling microstructure evolution.
Journal ArticleDOI
Ab initio study on plane defects in zirconium–hydrogen solid solution and zirconium hydride
TL;DR: In this article, the authors investigated the fracture properties of the hydride and showed that it has an extremely brittle nature due to the synergistic effect of a small γ S, implying easy generation of a fracture surface, and large γ US, implying a difficulty in dislocation motion.

The effects of misfit and external stresses on terminal solid solubility in hydride-forming metals
TL;DR: In this article, general expressions for the solubility of hydrogen in equilibrium with internally and externally stressed hydrides were derived for the TSS of zirconium and its alloys to estimate the amount of hydride-matrix misfit strain energy lost to plastic deformation.

Mechanisms of hydrogen induced delayed cracking in hydride forming materials
TL;DR: In this article, a quantitative model for hydrogen cracking in Zr-2.5 pct Nb is presented and compared with available experimental data, showing that the process occurs in an intermittent fashion; hydride clusters accumulate at the crack tip followed by unstable crack advance and subsequent crack arrest in repeated cycles.
