The relationship among slip systems, substructural energy density and evolution of Brass texture was established.
The α-fiber textures in the center layer rotated into Brass mainly through the activity of {111}<110> slip system.
The main texture in the surface layer was r-Cube with 96.3% reduction.
The high rolling temperature benefited the enhanced texture intensity of Brass component.
The low substructural energy density of Brass subgrain contributed to the development of Brass texture.
