中文摘要：
利用机械合金化方法制备了Mg76-xTi12Fe8Ni4Bx护0，1，2，3，4）合金并对其储氢性能进行了系统的研究。在Mg76-xTi12Fe8Ni4Bx（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。
英文摘要：
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 plateau pressure and decreases hydrogen absorption capacity and absorption/desorption rate.
