对铸态 RE(NiCoMnAl)5合金1173 K 退火、甩片、甩片＋1173 K 退火的工艺进行处理。合金通过XRD、SEM等分析发现，通过1173 K 退火及甩片＋1173 K退火后其成分变得更加均匀。电化学和动力学测试结果表明，铸态合金1173 K 退火及甩片＋1173 K退火具有良好的常温电化学性能，而铸态及甩片＋1173 K退火具有良好的低温放电性能，甩片＋1173 K退火处理合金具有最佳的综合电化学性能。
The effects of rapid quenching,1 1 7 3 K annealed and rapid quenching with 1 1 7 3 K annealed on the electrochemical performances of as-cast RE(NiCoMnAl)5 hydrogen storage alloys were comparatively investiga-ted to explore the optimal process.XRD,SEM analysis found that the composition become more homogenous after 1 173 K annealed.The results of electrochemical and kinetic measurement show that,the as-cast alloy of 1 173 K annealed and rapid quenching with 1 173 K annealed had the good electrochemical performance at room temperature,while the as-cast and rapid quenching with 1 173 K annealed had the good electrochemical per-formance at low temperature.It indicates the rapid quenching with 1 173 K annealed alloy had the best overall electrochemical properties.
