| 英文摘要 | The effects of equal-channel angular extrusion on the microstructure and mechanical properties of two binary alloys, Mg-1Gd and Mg-2Zn were studied by OM and EBSD. The results show that under the same extrusion conditions, Mg-2Zn alloy fully recrystallizes, resulting in grain growth and coarsening, and the strength and plasticity do not change with the number of extrusion passes. Mg-1Gd alloy only partially recrystallizes after extrusion, with a microstructure consisting of fine dynamic recrystallized grains and deformed grains. With the increase in the number of extrusion passes, the degree of recrystallization increases, leading to a doubling of the tensile strength and plasticity of Mg-1Gd alloy. This is related to the greater inhibition of recrystallization and grain growth by the solute atom Gd compared to Zn. The recrystallized grains have a dispersed orientation, while the grains that do not recrystallize in Mg-1Gd alloy have a c-axis orientation that deviates 45 degrees from ED to TD, which is consistent with the detection of macroscopic texture. A large number of small-angle grain boundaries form within the grains, and rotations around the c-axis occur on both sides of these boundaries, gradually evolving into large-angle boundaries. |
