摘　　要：用快淬法制备稀土贮氢合金Mm（NiCoAlMn）x（4．6〈x〈5．5）,研究了冷却辊转速、浇注速度、合金熔液保温时间等熔炼工艺参数对合金片晶粒尺寸的影响,经过短时间热处理，贮氢合金没有改变其纳米晶结构,在航模、低温镍氢电池的应用中，取得了令人满意的结果。The rare earth hydrogen storage alloy Mm（NiCoA1Mn）x（4.6〈x〈5.5） was prepared with rapidly quenched method. And it is studied that smelting technology parameters such as quenching roller speed, pouring speed, heat preservation time of alloy melt had effect on grain size of alloy flake, which didn＇t change its nanocrystalline structure after a little time heat-treated process. Satisfactory results were obtained when the alloy was applied in airplane-model or low temperature Ni/MH batteries.
