摘要
An unusual effect of Mn on the microstructures and mechanical properties of as-extruded Zn alloys has been found in our paper. Although the grain of Zn matrix is remarkably refined, and the number of MnZn13 compounds increases with the increasing of Mn contents, the volume fraction of the tensile twins obviously decreases. As a result, the tensile strength slightly decreases, and the elongation remarkably increases in as-extruded Zn-Mn binary alloys. This phenomenon is largely different from as-extruded Zn-based binary alloys containing Mg or Al. It means that the tensile twin largely signifies the comprehensive mechanical properties of as-extruded Zn-Mn alloys.
