| Zn-Ag, Zn-Mg, and Zn-Ag-Mg alloys with different compositions were successfully fabricated via the hot extrusion process. The effects of trace alloying elements Ag and Mg on the microstructure, mechanical properties and corrosion resistance of zinc-based alloys were studied. The results show that the microstructures of both Zn-Mg and Zn-Ag-Mg alloys are composed of the Zn matrix phase and Mg2Zn11 phase. The comprehensive mechanical properties of Zn-Ag-Mg alloy are superior to those of Zn-Ag and Zn-Mg alloys. Its tensile yield strength, tensile strength, elongation after fracture, compressive yield strength, compressive strength and Vickers hardness reached 276.27 MPa, 332.78 MPa, 15.60%, 208.33 MPa, 423.11 MPa and 96.04, respectively. The Zn-Ag-Mg alloy exhibits good corrosion resistance. |
