【摘要】 研究了五氧化二钒直接制备钒基固溶体贮氢合金的方法。分析测试了合金的化学成分、组织结构和贮氢性能。结果表明,用工业五氧化二钒可以合成钒基固溶体贮氢合金V3TiNi0.56Al0.2;PCT曲线表明该合金已具备平衡吸放氢的性能,吸放氢容量为1.8×10-4m3/g;合金中含有少量的氧化物夹杂,但通过真空感应精炼,可使夹杂含量降低。更多还原

【Abstract】 Direct synthesis of the vanadium-based solid solution hydrogen storage alloy with the industrial V₂O₅ is investigated.The chemical compositions,microstructures and hydrogen storage properties of the alloy are determined.The experiment result indicates that V₃TiNi 0.56 Al 0.2 can been produced taking V₂O₅,TiO₂ as raw materials and Alas a reductive agent.PCT curve indicates that the alloy has hydrogen storage capability,and the capacity is 1.8×10 -4 m³/g.Some oxide inclusions are also found in the alloy.After vacuum induction refining treatment,the amount of inclusions in the alloy decreases.更多还原
