摘要：
The hydrogen sorption of pure zirconium was investigated as a function of activation temperature. The sorption speed increased with activation temperature up to 750 K and decreased at higher temperatures. The X-ray photoelectron spectroscopy study revealed that oxygen peak virtually diminishes on heating at temperatures above 750 K. The cross-sectional TEM showed that the surface amorphous layer crystallizes on heating at 873 K. The structural transition from amorphous to crystalline state is attributed to the decrease in hydrogen sorption.
