英文摘要	we prepared ti1.4v0.6ni ribbons by arc-melting and subsequent melt-spinning techniques. ti1.4v0.6ni + x mg (x = 1, 1.5, 2, 2.5 and 3, wt.%) composite alloys were obtained by the mechanical ball-milling method. the structures and hydrogen storage properties of alloys were investigated. ti1.4v0.6ni + x mg composite alloys contained icosahedral quasicrystalline phase, ti2ni-type phase, beta-ti solid-solution phase and metallic mg. the electrochemical and gaseous hydrogen storage properties of alloys were improved with mg addition. ti1.4v0.6ni + 2 mg alloy showed maximum electrochemical discharge capacity of 282.5 mah g(-1) as well as copacetic high-rate discharge ability of 82.3% at the discharge current density of 240 ma g(-1) compared with that of 30 ma g(-1), and the cycling life achieved above 200 mah g(-1) after 50 consecutive cycles of charging and discharging. the hydrogen absorption/desorption properties of ti1.4v0.6ni + x mg (x = 1, 2 and 3, wt.%) alloys were better than ti1.4v0.6ni. ti1.4v0.6ni + 3 mg alloy also exhibited a favorable hydrogen absorption capacity of 1.53 wt.%. the improvement in the hydrogen storage characteristics caused by adding mg may be ascribed to better hydrogen diffusion and anti-corrosion ability. copyright (c) 2013, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved.
