چکیده
|
The ti 1.27fe + 11 wt.% ni composite synthesized by arc melting and ball milling and its possible use in hydrogen storage were studied. first the intermetallic ti 1.27fe was obtained from elemental powders of ti and fe by using the arc melting in argon atmosphere and was cracked in a reactor,after that nickel powder was added to the ti 1.27fe alloy before the milling. the mixture was subjected to high-energy ball milling to produce the ti 1.27fe/ni composite. nanocrystalline phases ti 1.27fe + ni were observed after 5 h of milling. hydrogenation results indicated that in the first cycle of hydriding the maximum amount of hydrogen release was 2.10 wt. for the composite at 100°c,under hydrogen pressure of 0.8 mpa and without prior activation. © 2013 j. bonifacio-martínez et al.
