摘      要：Nanostructured Mg-3Ni-2MnO_(2) was synthesized by ball milling elemental powders of Mg,Ni and MnO_(2) in hydrogen *** microstructures of the powder prepared at different milling time were analyzed by X-ray diffractometry(XRD), scanning electron microscopy(SEM)and high resolution electron microscopy(HREM).The milling time is the most key parameter impacting on the grain size and the microstructure of *** prolonging the milling time,particle size becomes smaller and *** after the ball milling time reaches about 20 h,reduction of grain size becomes *** the milling time is more than 50 h,nanocrystalline fully *** the milling time is more than 80 h,there are more amorphous phases in *** average particle diameter of material is about 1μm and the grain size is 10-30 nm.
