چکیده انگلیسی
The diffusion of hydrogen in the tetrahedral interstitials of bulk spherical Laves phase ZrMn0.85Cr0.1V0.05Fe0.5Ni0.5 and ZrMn0.85Cr0.1V0.05Fe0.5Ni0.5 + 1 wt% B alloys has been studied in the α-phase (solid-solution) region over the temperature range 450-650 °C, for hydrogen pressures up to 100 mbar using Sieverts-type apparatus. The diffusion constants have been determined from the gas-solid reaction, where the gas pressure dependence on time has been measured at fixed temperature. The results have been discussed on the basis of Fick's law of diffusion. The dependence of diffusion constant on alloy composition and initial pressure has been evaluated. Activation energy has been obtained from the temperature dependence of diffusion using Arrhenius relation.
