Abstract：

The influences of roll forming process on the microstructure and mechanical properties of 6061-T6 aluminum alloy sheets were investigated by finite element simulation analysis, electron back scatter diffraction (EBSD) and microhardness experiments. Firstly, a finite element simulation model for the roll forming process of 6061-T6 aluminum alloy was established, and the stress and strain changes during the roll forming process were analyzed by combining experiments with simulations to determine the different mechanical responses at the inner and outer edges of bending corner area, and the effectiveness of the simulation model was verified, which clarified the characterization position for the subsequent microstructure analysis. The macroscopic analysis results show that the springback angle of 6061-T6 aluminum alloy is positively correlated with the target forming angle, and the hardness of he forming area is significantly improved after roll forming. The microscopic analysis results show that with the increasing of forming angle, the grains at the inner and outer edges of the material are significantly refined, and the texture type shows a trend of changing from random to gradually consistent, and finally consists of sharp Cube texture and strong {111}<112> texture.
