The result shows that the hydrogen storage properties increase remarkably after pure magnesium ball-milled with 10% TiFe(subscript 1-x)Cr (x=0, 0.3). Moreover, the chromium content also influences the hydrogen storage characteristics. Furthermore, the ball-milled composite of Mg+10%TiFe0.7Cr0.3 has the best hydrogen storage properties with hydrogenation capacity of 7.14% and dehydrogenation capacity of 6.91% at 613 K. In addition, the lower temperature of 493-573 K, the Cr-contained composite exhibits the best dehydrogenating kinetics.
