摘要

In the present study, mechanical alloying technique was used to prepare (Mg2Ni)100-xTix (x = 0, 2.5, 5, 7.5, and 10 wt.%) powders starting from elemental powder mixture under an Ar atmosphere. The experimental results showed that the absorbed hydrogen content and reversible hydrogen content was 3.14 and 2.40 wt.% for 15 h milled Mg2Ni powders, respectively. The maximum hydrogen absorption content was increased to over 3.8 wt.% with Ti additions. The reversible hydrogen content also increased significantly (18-25%) with Ti additions. Meanwhile, 15 h milled Mg2Ni-Ti powders can absorb more than 3 wt.% of hydrogen within 1000 s. Not only the hydrogen absorption ability but the hydrogen absorption rate were improved by the additions of titanium and MA treatment in Mg2Ni alloy.
