采用熔炼法加球磨处理制备Mg_2Ni_(1-x)Cu_x (x=0, 0.2, 0.4)合金.通过XRD和SEM/EDX对合金的相成分和微观组织进行分析.研究表明,3种合金中都有Mg_2Ni相形成.随着Cu含量的增加,合金分别形成Mg_2Cu相和Cu_(11)Mg_(10)Ni_9相.PCT测量结果表明,Cu的添加可以改善合金的吸放氢性能.
採用鎔煉法加毬磨處理製備Mg_2Ni_(1-x)Cu_x (x=0, 0.2, 0.4)閤金.通過XRD和SEM/EDX對閤金的相成分和微觀組織進行分析.研究錶明,3種閤金中都有Mg_2Ni相形成.隨著Cu含量的增加,閤金分彆形成Mg_2Cu相和Cu_(11)Mg_(10)Ni_9相.PCT測量結果錶明,Cu的添加可以改善閤金的吸放氫性能.

Mg_2Ni_(1-x)Cu_x alloys (x=0, 0.2, 0.4) were synthesized by two steps: induction melting and then ball milling. The composition and microstructure of the alloys were analyzed by XRD and SEM/EDX, respectively. Mg_2Ni phase was observed in all of the 3 alloys. The increase of Cu amount led to the formation of Mg_2Cu phase and Cu_(11)Mg_(10)Ni_9 phase. The hydrogen absorption/desorption properties were tested on PCT measurement apparatus, and the results show that the hydrogen absorption/desorption properties of the alloys can be improved by the addition of Cu.
