主　　题：Mg_(2)Cu mechanical alloying nanocrystalline discharge capacity 

摘      要：The effect of Mg replacement with Al on the discharge capacity of Mg_(2)Cu powder mixture was *** mixture of nano-crystalline powder was prepared via mechanical alloying(MA)technique with a high energy planetary ball *** addition,different moles of Al(0.05,0.1,0.15,0.2,and 0.3 M)were substituted to Mg_(2)Cu powder.X-ray diffraction(XRD),scanning electron microscopy(SEM),and transmission electron microscopy(TEM)were used to analyze changes in structure,morphology,and grain *** obtained powder was utilized as an anode in a nickel-metal hydride battery(Ni-MH).In the specimens with 0.05 M Al content,the orthorhombic structure of Mg_(2)Cu is emerged after 5 h *** results reveal that more than 0.1 M Al substitution leads to an appearance of MgCu_(2) *** substi-tution does not affect microstructure uniformity;however,it causes a decrease in crystalline size and lattice *** selected area diffraction(SAD)pattern elucidates that the electrode with the Mg_(1.9)Al_(0.1)Cu chemical composition and 20 h milling has the maximum discharge capacity.
