| 摘 要： | 利用机械合金化方法制备了Mg76-xTi12FesNi4Bx(x=0,1,2,3,4)合金并对其储氢性能进行了系统的研究.在Mg76-xTi12FesNi4Bx(x=0,1,2,3,4)合金中,Mg2Ni和NiTi是主要的合金相.B的加入使合金的非晶化程度提高,也降低了合金的吸放氢温度和滞后效应,但吸放氢平台有所上升,合金的吸氢量以及吸放氢速率均有下降.

| Abstract: | Mg76-xTi12Fe8Ni4Bx (x=0, 1, 2, 3, 4) alloys were prepared and the effects of substitution of B for Mg on hydrogen storage performances of the alloys were investigated. In the alloys, Mg2Ni and NiTi are main phases and the amorphous degree increases gradually with amount of B content increasing. Partial substitution of B for Mg can decrease the temperature of hydrogen absorption reaction and hysteresis effectively. On the other hand, substitution of B for Mg increases the hydrogen absorption/desorption plate... |
