Abstract

Mg+10%TiFe

1-x

(x=0

0.3)multi-phase alloys and pure magnesium were composed by high energy mechanical milling

and their hydrogen storage characteristics were investigated comparatively. The result shows that the hydrogen storage properties increase remarkably after pure magnesium ball-milled with 10% TiFe

1-x

(x=0

0.3). Moreover

the chromium content also influences the hydrogen storage characteristics. Furthermore

the ball-milled composite of Mg+10%TiFe

0.7

0.3

has the best hydrogen storage properties with hydrogenation capacity(mass fraction)of 7.14% and deh

ydrogenation capacity of 6.91% at 613 K. In addition

at the lower temperature of 493 - 573 K

the Cr-contained composite exhibits the best dehydrogenating kinetics. The analysis with X-ray diffraction(XRD)

scanning electron microscopy(SEM)

and energy dispersive spectrometer(EDS)indicates that the fine TiFe

1-x

particles distribute on the surface of magnesium base

acting as some catalysis sites

which improves the hydrogenating and dehydrogenating properties.
