DIFFUSIVITY OF HYDROGEN IN STEELS AT LOW TEMPERATURES
氢在钢中低温扩散系数

The curves of hydrogen permeation in steels of A3, 08F, 16MnR and 20G were determined at temperatures between 293 K to 328 K by Devanathan-Stachurski cell. The Arrhenius equations of hydrogen diffusion coefficient versus temperature were found out. The equations may provide important fundamental parameters for monitoring the susceptivity of hydrogen induced crack while the steels are used in various industrial environments.
