摘　　要：稀土储氢合金是研究最早的储氢合金,也是目前仅有大规模产业化的储氢合金。本文综述了近年来稀土储氢合金的研究进展。介绍了稀土储氢合金的主要制备方法,例如感应熔炼、电弧熔炼、真空磁悬浮熔炼等以及较为新颖的自燃燃烧法;总结了改性处理方法,如热处理、表面处理等;分别讨论了AB5型、R-Mg-Ni系稀土储氢合金的元素组成变化对合金性能的影响。Rare earth-based hydrogen storage alloys are the first developed hydrogen storage alloys and the only hydrogen storage alloys applied in a large scale now.This review is devoted to review the progress in rare earth-based high performance hydrogen storage alloys.The preparation methods,such as induction melting,arc melting,vacuum magnetic levitation melting,and a novel method self-ignition combustion synthesis,are introduced.The modification treatment methods,such as heat treatment and surface treatment,are summarized.And the relevance between the composition and the performance of AB5-type and rare earth-Mg-Ni-based hydrogen storage alloys are discussed respectively.
