采用拉伸试验机、光学显微镜（OM）、扫描电镜（SEM）、透射电镜（TEM）和X射线衍射仪（XRD）研究了Zn对含有中等数量富Fe相颗粒的Al-Mg-Si-Cu合金的显微组织、织构演变和力学性能的影响。结果表明，Zn的加入对合金的最终力学性能有显著影响，但对显微组织和最终再结晶织构影响不大。Zn的加入有利于提高合金的屈服强度、抗拉强度和延伸率，但不利于提高合金的强度和降低Δ r值。在形变热处理过程中，合金的显微组织几乎与Zn的加入无关。而Zn的加入可以阻止中间退火过程中第二相粒子的析出。与不含Zn的合金板相比，含1.0wt% Zn的合金板在最终冷轧之前总是具有较弱的织构，但在经历最终冷轧之后具有较强的织构。固溶处理后，它们几乎具有相同的再结晶织构。最后讨论了Zn的加入对再结晶织构的影响。它们相似的再结晶织构归因于中等数量的富Fe相颗粒所形成的相似的显微组织。
The effect of Zn on the microstructure, texture evolution and mechanical properties of Al-Mg-Si-Cu alloys with a medium number of Fe-rich phase particles was investigated using tensile testing machine, optical microscopy (OM), scanning electron microscope (SEM), transmission electron microscope (TEM) and X-ray diffractometer (XRD) in the present study. The results show that Zn addition has a significant influence on the final mechanical properties, but a slight effect on microstructure and final recrystallization texture. Zn addition is favorable to increase yield strength, ultimate tensile strength and elongation, however it is detrimental to improvervalue and reduce Δrvalue. During the thermomechanical processing, the microstructure almost has nothing to do with Zn addition. However, Zn could prevent the secondary phase particles from precipitating during intermediate annealing. In contrast to the alloy sheet without Zn, the alloy sheet with 1.0 wt% Zn always has weaker textures before final cold rolling, but a stronger texture after experiencing final cold rolling. After solution treatment, they almost possess the same recrystallization texture. Finally, the effect of Zn addition on the recrystallization texture was discussed. Their similar recrystallization texture can be attributed to the similar microstructure, which was caused by the medium number of Fe-rich phase particles.
