摘要：

The microstructure, electrical conductivity and electromagnetic interference shielding effectiveness of Mg-X (X=Al, Sn, Y and Gd) alloys in as-cast and solution states were systematically investigated in this study. The electrical conductivity and electromagnetic shielding capacity of binary magnesium alloys decrease linearly with alloying element content. The electromagnetic shielding effectiveness of the binary magnesium alloys with the same alloying element content is as follows: Mg-Gd<Mg-Sn<Mg-Y<Mg-Al. The main reason for the differences in electromagnetic interference shielding of the binary magnesium alloys is the change in conductivity, which is mainly affected by volumetric difference of solute atoms and magnesium atoms, solute atomic valence and configuration of extranuclear electron.
