摘　　要：参照含Nb锆合金中第二相的成分,熔炼了(Zr,Nb)_2Fe,Zr(Nb,Fe)_2和β-Nb合金.成分测试结果表明,所炼合金的成分与锆合金中的第二相相同.XRD分析结果表明,除(Zr,Nb)_2Fe外,Zr(Nb,Fe)_2和β-Nb合金的相结构也与锆合金中的第二相相同.备合金的压力-成分-温度(P-C-T)曲线和吸放氢动力学曲线表明,3种合金和纯Zr的可逆吸放氢能力按Zr(Nb,Fe)_2,(Zr,Nb)_2Fe,β-Nb和Zr顺序依次减弱.Referring to the compositions of the second phases in zirconium alloys,（Zr,Nb）2Fe, Zr（Nb,Fe）2 andβ-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 andβ-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（H（rev）） decrease in the sequence of Zr（Nb,Fe）2, （Zr,Nb）2Fe,β-Nb and Zr.
