The phase field model for hydrogen diffusion and γ-hydride precipitation in zirconium under non-uniformly applied stress

This special issue contains papers, which were selected from the presentations at the International Symposium on Macro-, Meso-, Micro- and Nano-Mechanics of Materials (MM2003), held on December 8–10, 2003 at the Hong Kong University of Science and Technology (HKUST), Hong Kong.Zirconium and its alloys are primary structure materials in nuclear industry. They often absorb hydrogen from environment and form hydrides. This will cause degradation of the materials. In this work, the hydrogen diffusion and hydride formation process near a blunt notch in a continuum media have been simulated by phase field models. The results agree with the experiments.Department of Mechanical Engineerin
