Description
We report the first straightforward measurements of the diffusion coefficient of hydrogen migrating in icosahedral (i-) quasicrystal ribbons of Ti45Zr38Ni17 and in two-phase bulk samples containing both the i-phase and the Laves phase. It is found that at 273-353 K diffusion obeys Arrhenius's law with activation energy 0.24 eV and that the ratio of the volumes of the phases changes at hydrogenization
