The Mg35Ti65 hydrogen storage alloys were prepared by high-energy ball-milling,which added 10wt.% La0.4Ce0.1Pr0.3Nd0.2Ni4Co0.5Mn0.3Al0.2 as a modifier.The effects of modifier addition and milling time on the microstructure,hydrogen absorption properties of the alloys were studied.The results showed that the single BCC solid solution can be obtained after the Mg35Ti65 alloy was milled for 20h.Adding 10wt% modifier and milling for 0.5h,the hydrogen storage properties were obviously improved and its hydrogen storage capacity reached to 3wt.% at 8MPa hydrogen pressure and 573K within 100s.As increase of ball-milling time,the phase structure of Mg35Ti65 hydrides changed,the hydrogen absorption capacity and kinetics became worse gradually.
