抄録

This paper deals with the effects of applied tensile stresses on the diffusion coefficient of hydrogen.<BR>In the present ivestigation, measurements were carried out for the hyrdogen flow through cylindrical steel tubes subjected to tensile stresses. Hydrogen was charged cathodically at the external surface of the tube, and hydrogen gas permeating at the internal surface was collected and measured by glycerin method.<BR>The experimental data were analyzed by using the Time-Lag method. The results obtained are summarized as follows;<BR>(1) Hydrogen diffusivity depends upon the applied tensile stress. The hydrogen diffusion coefficient in steel increases with an increase in the applied stress.<BR>(2) The solubility of hydrogen is 45 cc/100g Fe.<BR>(3) From this result, it is assumed that hydrogen diffusion process interacts with various defects within the matrix of metal.
