摘要：

In nanocrystalline Fe90Zr10 produced by crystallization of melt-spun amorphous ribbons, the dependence of the local relaxation processes as well as the long-range diffusion kinetics on the hydrogen concentration was studied by magnetic after-effect measurements and thermal desorption experiments, respectively. The hydrogen-induced local relaxations and the macroscopic degassing can be assigned to hydrogen diffusion in grain boundaries and are well described by a potential with a distribution of site as well as saddle-point energies similar to the amorphous structure of Fe90Zr10.
