| 摘 要： | Ti/Cr (atomic ratio 3:4) amorphous alloy was prepared by ball milling the rapidly quenched Ti/Cr ribbons for 30h, and then milled with MgH_2 for 50 h under Ar atmosphere to obtain MgH_2-30wt. % Ti/Cr composite. The XRD results indicate that MgH_2 decomposed partly during ball milling process. The brittle MgH_2 and the mechanical driving force resulted in a highly dispersive distribution of the Ti/Cr amorphous phase in the Mg matrix. The favorable hydrogenation performance is mainly attributed to the combined effects of the catalytic efficiency of Ti/Cr amorphous alloy and defects on the surface and/or in the interior of Mg formed during ball milling process.
