Aiming at the bottleneck problems of long process flow and high cost of traditional magnesium alloy sheet preparation, commercial Mg-1.5Mn-0.3Ce alloy sheet was prepared by extrusion and subsequent single-pass rolling process, and its microstructure and mechanical properties were systematically studied. The results show that the strength of the extruded Mg-1.5Mn-0.3Ce alloy rolled at 250 ℃ increases with the increase of single-pass deformation amount. With 48% deformation amount, the alloy has the highest strength in the transverse direction. The yield strength and tensile strength reach 242.9 MPa and 270.0 MPa, respectively, and the elongation after fracture is ~11.8%. After rolling with 48% deformation amount, the grain size is refined from 6.2 to 2.6 μm. A large number of nano-sized α-Mn and Mg12Ce particles are dispersed in the sheet, and high-density residual dislocations are accumulated around the nano-sized second phase particles, which improve the strength of the rolled alloy. Therefore, this work can provide a favorable reference and basis for the the preparation process optimization of low-cost and high-performance magnesium alloy sheets.
