摘要：
The hydrogen relaxation peak in 2179 austenitic stainless steel charged by high pressure gas has been studied. The thermal activation parameters of the peak were compared with those of H diffusion in the steel. The differences are discussed on the basis of an atom pair reorientation model. The annealing process of the peak was analyzed theoretically. A comparison of the experimental results with the theoretical analysis suggests that this peak is probably produced by a hydrogen-substitutional atom pair.
