| 英文摘要 | This study investigated the effect of rolling step reduction on the anisotropy of Al-Zn-Mg-Cu alloy plates. The results indicate that the grains of the rolled Al-Zn-Mg-Cu alloy plates, subjected to a total rolling reduction of 70 %, exhibited distinct fiber streamline characteristics, thereby demonstrating significant anisotropy. In the scenario of small step reduction rolling (7 passes), the yield strength of the plate in the transverse direction was found to be 9 % lower, and the elongation was 30 % lower compared to that in the rolling direction. An increase in rolling step reduction resulted in alterations to the primary texture types, leading to an enhancement in both yield strength and elongation of the plate in the transverse direction to a certain extent. However, excessive step reduction (3 passes) resulted in a high dislocation density and the formation of numerous subgrain boundaries within the grains, which facilitated the coarsening of precipitates and ultimately resulted in a decrease in strength. By implementing a medium step reduction (5 passes), both high strength and restrained anisotropy could be achieved, thereby minimizing the differences in yield strength and elongation between the transverse and rolling directions to 4 % and 12 %, respectively. |
