摘要: The influences of rare earth elements (cerium and lanthanum) on the microstructure phases Al-3.0 wt%Mg alloys used for electromagnetic shielding wire were characterized by scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD) differential calorimetry (DSC). mechanical properties electrical resistivity also investigated. results indicated that a certain content could improve purification aluminum molten, enhance strength, reduce alloys. strength reached top value when RE was 0.3 wt% while alloy with 0.2 addition had smallest resistivity. elongation varied little no more than wt%. But excessive would be harmful to
