| 英文摘要 | The dynamic recrystallization (DRX) behavior and mechanical properties of WE43 magnesium alloy during hot rolling rather than hot compression at 400-500 C were systematically investigated by electron backscattering diffraction (EBSD) analysis. At relatively low temperatures, such as 400 ?, the rolled sheets cracked, and no DRX grains were found, and twinning contributed more to the plastic deformation. However, when the rolling temperature was above 450 ?, the alloy exhibited an excellent rolling ability, and slip dominated the plastic deformation. In parallel, the recrystallization mechanism involved continuous dynamic recrystallization (CDRX), where grains nucleated along the original grain boundaries and geometrically necessary dislocations (GNDs) occurred within the parent grains. In addition, a few twin-induced recrystallization grains were observed in the early stage of the rolling process at 500 ?. Rolled sheets at suitable temperatures have similar strength and fracture elongation and do not exhibit obvious anisotropy. This can be attributable to the random orientation of the DRX grains and similar Schmid factor (SF) values of different loading directions at different rolling temperatures. |
