The effects of Al(Fe,Mn)Si particles controlled by different hot-rolling deformations on the microstructure evolution, texture evolution, and formabilities of Al-Mg-Si-Zn alloy were systematically investigated using OM, SEM, TEM, XRD, and tensile tests. The results indicate that Al(Fe,Mn)Si particles with different size and number distribution characteristics can be obtained by adjusting the hot-rolling deformation degree (59%, 74% and 87%), and these differences in particle distribution are the main factors affecting the recrystallization nucleation and grain growth during solution treatment. After T4P treatment, the grain orientations in the Al-Mg-Si-Zn alloy sheets with 59% and 74% hot-rolling deformation tend to be randomly distributed. In comparison, the sheet with 87% hot-rolling deformation consists of R{124}á211？, Cube_ND{100}á013？, Copper{112}á111？ and Brass{011}á211？ texture components. The medium size and number of Al(Fe,Mn)Si particles obtained at 74% hot-rolling deformation cause fine grains and randomly distributed texture, which significantly improves the formability of Al-Mg-Si-Zn alloy.
