抄録

The effect of the residual plastic strain on the diffusivity of hydrogen was studied by means of the occlusion test and permeation test.<BR>Specimens were strained in four stages by plastic deformation. (residual plastic strain ε=4% 8%, 12% and 16%)<BR>Hydrogen was charged cathodically.<BR>From the results of these tests, it was found that the hydrogen diffusivity depends upon the residual plastic strain. Generally, hydrogen diffusion coefficient increases with an increasing strain.<BR>From these results and previous work, it is considered that diffusion coefficient of hydrogen in steel specimen under various applied stress or strain increases within the order of 10^-7 and 10^-6 cm²/sec.
