(~1–2 μm). EDS analysis of the annealed alloy is displayed at 250°C. Elemental analysis of both grains and grain
in Figure 9c, revealing a continued enrichment of Mg at boundaries of the alloy annealed at 300°C, as displayed
the grain boundaries. In Figure 9d, the grain size of the in Figure 9e, indicated that the Mg concentration in the
Zn–Mg alloy annealed at 300°C for 0.5 h was reduced to α-Zn matrix and at the grain boundaries was 0.21% and
approximately 1 μm, compared to that of alloys annealed 3.17%, respectively. At an annealing temperature of 300°C,
