摘要：
The homogenized 2024 aluminum alloys were hot rolled at different final rolling temperatures, and they were naturally aged for 4 days after solid solution treatment. The effects of final rolling temperature on the mechanical properties and intergranular corrosion behavior of 2024 aluminum alloy were investigated by electron backscatter diffraction (EBSD), X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemistry tests. The results show that there are shear textures and a small amount of recrystallization texture in rolled 2024 aluminum alloy, while some typical rolling textures appear after solid solution. The final rolling temperature affects the structure and texture changes of the alloy. When the final rolling temperature is low (207 ℃), the average grain size of the alloy is small, the average Schmid factor is low, and the strength is high; when the final rolling temperature is high (280 ℃), the proportion of low angle grain boundary and {111} plane texture is high, the texture content with large Schmid factor is small, and the intergranular corrosion resistance is excellent. © 2023 Cailiao Daobaoshe/ Materials Review.
