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.
(Zr, Nb) _2Fe, Zr (Nb, Fe) _2 and β-Nb alloys were melted with reference to the composition of the second phase in the Nb-containing zirconium alloy.The results of the component tests showed that the composition of the refined alloy and the The results of XRD analysis show that the phase composition of Zr (Nb, Fe) 2 and β-Nb alloys is the same as the second phase of zirconium alloy except (Zr, Nb) (PCT) curves and kinetics of hydrogen absorption and desorption show that the reversible hydrogen evolution and desorption capacities of the three alloys and pure Zr are in order of Zr (Nb, Fe) 2, (Zr, Nb) 2Fe, β-Nb and Zr Weakened.
