Effects of self-induced stress in tubular membranes during hydrogen diffusion

摘要

Various effects induced by self-stress during hydrogen diffusion across metallic tabular membranes are discussed. The up-hill diffusion in the initial time of permeation, the time course of inner pressure change, the steady distributions of hydrogen concentration and residual stress in membranes, and the acceleration of permeation rate on interruption of hydrogen charging are properly interpreted.
