English abstract
The formation of hydrides in zirconium alloys will cause degradation of the materials. Despite extensive study, the mechanisms and effects of hydrogen embrittlement have remained unclear. In this report, we had presented the calculation results of mean-field strain by different hydride phases in zirconium alloys, like δ-hydride and γ-hydride. The results of δ-hydride are compared with experimental data obtained by X-ray diffraction method by Bai et al.\cite{Baib} and note \cite{Ali} of Massih. The result of δ-hydride is identical with Massih but have some differences with Bai et al. We had also compared our calculated mean-field strain by γ-hydride with δ-hydride. The γ-hydride showed lower value than δ.
