摘要
Hydrogen permeability through beryllium at the pressures of up to 21 atm and temperatures of up to 650 degree C was studied on pipes and disks obtained from powdered hot-pressed beryllium. The temperature dependendence of hydrogen permeability through beryllium and energy of activation of the process is established. Hydrogen permeability through beryllium is lower than for such construction materials as iron, stainless steels, and molybdenum. Hydrogen permeability of beryllium decreases with a decrease in the size of the initial powder.
