The kinetics of hydrogen absorption in Zr alloys containing Nb and Ta admixtures (10 wt% Nb, 12 wt%Ta and 10 wt%Nb and 12 wt%Ta) is addressed. Hydrogen absorption is measured in the temperature range 400-700 degrees C at hydrogen pressure 1 bar using the volumetric method, and a kinetic analysis is performed to determine the mechanisms and rates of hydrogen absorption. To get further insight into hydrogen diffusivity in zirconium hydride, H-1 NMR spectroscopy is used to provide the activation energies for proton jumping in the studied samples. The tantalum is found to dominantly influence the surface reactivity, while niobium influences large decrease of the activation energy for hydrogen diffusion in the bulk of zirconium hydride. This behavior is linked to the information on the structure of the alloys obtained by XRD. Copyright.(C) 2015, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.
