摘      要：To accelerate the development and design of magnesium(Mg)alloys,the structural and mechanical properties of important precipitates in Mg−Zn alloys were studied by experiments and density functional *** nano-indentation tests revealed that the hardness of the precipitates initially increased and then decreased with increasing Zn content,and was significantly higher than that of pure Mg and *** calculation results revealed that the precipitates stability initially increased and then decreased with increasing Zn *** bulk moduli of the precipitates increased,whereas their shear and Young’s moduli initially increased and then decreased with increasing Zn *** decreasing order of ductility for these compounds is MgZn_(2)>Mg21Zn_(2)5>Mg2Zn11>*** surface profiles of the compounds revealed that they are obvious *** the degree of covalency and bond length of covalent bonds initially increased and then decreased with increasing Zn content.
