摘要：

In order to model hydrogen transport during plastic deformation, it is essential to take into account the combined effect of the interaction of hydrogen with newly generated dislocations, the interactions between hydrogen in lattice sites and moving dislocations, and the effect of both of these on the diffusion process. Both atomistic and macroscopic diffusion models have been developed. The results show that the hydrogen flux due to moving dislocations depends upon the kinetics between hydrogen in moving dislocations and that in the lattice. The dynamic trapping effect, i. e. trapping associated with an increase in the population of dislocations, should also be taken into account.
