The kinetics of hydrogen absorption in Zr-based alloys Zr–2.5Nb, Zr–10Nb, Zr–2.5Nb–3Ta and Zr–10Nb–12Ta have been investigated in the temperature range 673–973 K at 1 bar hydrogen pressure. The improvement in hydrogen kinetics and a slight decrease of maximal amount of hydrogen absorbed were observed upon cycling. The rate determining steps are as follows: geometrical contraction for all samples except Zr–10Nb–12Ta; diffusion in the beginning for Zr–10Nb at 973 K Zr–2.5Nb–3Ta at 673 K and 973 K; first order reaction Zr–10Nb–12Ta at all temperatures. The amount of additives, Nb and Ta, is found to have major influence on the mechanism of the absorption process.
