with approximately 20 μm in thickness formed on the surface of zirconium hydride acts as an effective diffusion barrier. Key words: zirconium hydride; gas phase analysis(GPA); hydrogen desorption... their hydrogen desorption behaviors because they form an efficient diffusion barrier. The dense layer serves as a protective barrier against hydrogen releasing. Hydrogen not only has to diffuse through......

radius of 0.15 mm after hydrogen charging. Meanwhile, the hydrogen diffusion behaviors of various strength steel were studied by thermal desorption spectroscopy (TDS) analysis. The SSRT results show... the susceptibility of hydrogen embrittlement [13, 14]. And hydrogen diffusion in the steel has been also difficult to be experimentally determined recently, especially for notched parts [15]. The hydrogen......
