Abstract

The microstructural evolution of Al-Zn-Mg-Cu alloy under different stress and aging temperature was studied using cold compression and heat treatment. The relationship between the process parameter and the microstructure of the material was analyzed by OM, EBSD, and TEM. The results showed that the grain size decreased and the recrystallization fraction increased with the increase of compression. Textures of <111>||X (cubic), <110>//Y, Goss have higher intensity after solution treatment, but their intensity and proportion also decrease with the increase of compression. η' is the main precipitate in the alloy aged at 140 °C, while η is the main precipitate in the alloy aged at 160°C. Precipitation coarsening and grain refinement affect the microhardness of the alloy together.

冷压和热处理对 Al-Zn-Mg-Cu 合金显微组织和力学性能的影响 Al-Zn-Mg-Cu 合金的组织和力学性能

通过冷压缩和热处理，研究了铝锌镁铜合金在不同应力和时效温度下的微观结构演变。通过 OM、EBSD 和 TEM 分析了工艺参数与材料微观结构之间的关系。结果表明，随着压缩量的增加，晶粒尺寸减小，再结晶部分增加。X（立方体）、//Y、Goss 纹理在固溶处理后具有较高的强度，但其强度和比例也随着压缩率的增加而降低。沉淀粗化和晶粒细化共同影响合金的显微硬度。
