摘要：

The ball-milling method was used to produce Mg-50 wt.% ZrFe1.4Cr0.6 composite. The thermodynamic, kinetic, and cycling properties, as well as the resistance to oxidation were examined. This composite possesses excellent kinetic properties, even at moderate temperature. Scanning electron microscopy, energy-dispersive spectrum transmission electron microscopy and X-ray diffraction were used to characterize the composite before and after hydriding. The fine ZrFe1.4Cr0.6 particles covering Mg particles acting as a "catalytic film", a significant amount of imperfections and some alloy powder in the Mg matrix introduced by ball milling all contributed to the enhanced absorption/desorption rate.
