内容記述 | The expression of apparent diffusivity of hydrogen in a generalized trap model of "two energy level" has been obtained on the basis of an assumption of a system of low occupation probability of hydrogen on normal lattice and trap sites. A good point of the derived apparent diffusivity of hydrogen compared with the conventional expression is as follows: (i) The traps have not only the characteristic trap density and depth but also the trap "width". (ii) The peculiar trapping and release rates are taken into consideration in the sites involved. (iii) It is taken into account that the characteristic diffusivity within the traps as well as the dimension of trap, and those of normal lattice site can affect the total diffusion flux. The validity of the resulting apparent diffusivity equation has been examined on the experimental data of cold worked specimens of palladium, nickel, iron and Pd-Ag solid solutions in which the dissolved silver atoms in palladium are expected to act as traps for hydrogen atoms. | |||||
