摘要	This parper reports a simple extrusion pathway for fabricating Zn–1Mg alloy with a bimodal structure. The alloy was prepared by casting and extruding at 200 °C and an extrusion ratio of 25:1. Microstructure and mechanical properties of the Zn–1Mg alloys were systematically investigated using OM, XRD, SEM, EBSD, TEM, and tensile tests. The results show that the Zn–1Mg alloy consisted of primary α-Zn dendrites and a three-component eutectic structure of α-Zn + Mg2Zn11 + MgZn2. The yield strength, ultimate tensile strength and elongation of extruded alloy at room temperature reached ∼289 MPa, ∼320 MPa, and ∼32%; and the average size of fine grains and coarse grains were ∼1.65 and ∼6.84 μm, respectively. Besides, dynamic recrystallization occurred during hot deformation, and particles in the broken phase were effective sites for the nucleation of dynamic recrystallized grains nucleation via a particle-stimulated nucleation mechanism. © 2022 Elsevier B.V.
