【摘要】 采用XRD物相分析、扫描电镜分析、透射电镜分析及电化学性能测试等方法，分别对铸态及快淬态Laves相Zr基AB₂型储氢合金进行了组织结构及电化学性能方面的研究，结果表明，铸态合金由C15-Laves相，C14-Laves相及非Laves相Zr₉Ni₁₁（AB₂-1中）、Zr（Ni，Mn）Sn_0.35（AB₂-2和AB₂-3中）组成，AB₂-1的电化学性能明显好于另外两种合金。合金经过快淬处理后，由于部分非晶化，对电极的放电容量和活化性能都有严重的不良影响。更多还原

【Abstract】 The microstructures and electrochemical properties of as - cast and quenched Laves phase Zrbased AB₂ hydrogen storage alloys were investigated by XRD、SEM、TEM and electrochemical properties testing in this paper. The result indicates that the as - cast alloy is composed of cubic C15 Laves phase, hexagon C14 Laves phase and non - Laves phases such as Zr₉Ni₁1 （ in AB₂ - 1 ）、Zr（Ni, Mn） Sn_0.35（ in AB₂ - 2 and AB₂ - 3 ） The electrochemical properties of AB₂ - 1 alloy is better than AB₂ - 2 and AB₂ - 3 alloys’ . The electrochemical properties of quenched alloys are poor because of part amorphous existence.更多还原
