Description
Summary:The article presents the results of the study of microstructure, mechanical properties, corrosion resistance and fatigue strength of the Zn-1%Mg and Zn-1%Mg-0.1%Ca alloys, processed by rotary swaging (RS). It is shown that the grain refinement leads to an increase in the strength of the alloys up to 196 ± 4 and 218 ± 6 MPa for the Zn-1%Mg and Zn-1%Mg-0.1%Ca alloys, respectively. The ductility of the Zn-1%Mg and Zn-1%Mg-0.1%Ca alloys also increases up to 5.7 ± 2.2 and 7.0 ± 0.7%, respectively. The structure caused by RS does not affect the corrosion potential of both investigated alloys, but changes the corrosion current density, decreasing it for the Zn-1%Mg alloy and increasing it for Zn-1%Mg-0.1%Ca. The fatigue limit of the Zn-1%Mg and Zn-1%Mg-0.1%Ca alloys after RS is equal to 115 MPa and 130 MPa, respectively.
