Abstract Referring to the compositions of the second phases in zirconium alloys, (Zr, Nb)2Fe, Zr(Nb, Fe)2 and $\beta$--Nb were prepared. Chemical composition analysis results indicated that the compositions of the experimental alloys are the same as those of the second phases in zirconium alloys. XRD analysis indicated that the structures of Zr(Nb, Fe)2 and β-Nb alloys are the same as the second phases in zirconium alloys. The pressure-composition-temperature (P-C-T) curves and kinetic curves of hydrogen absorption and desorption were obtained. Experimental results showed that the reversible hydrogen absorption and desorption abilities (Hrev) decrease in the sequence of Zr(Nb, Fe)2, (Zr, Nb)2Fe, β-Nb and Zr.
