Abstract

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.
