| The formation of the ears on the drawn cups of the annealed low carbon steel was interpreted by the development of the recrystallization textures. The annealing textures depended on the degree of cold rolling reductions. The inhomogeneous textures were developed through the layers of steel sheet. The 4-fold and the 6-fold ears at the drawn cups were related to the {111}//ND fiber orientations, respectively. The assumption that the amount of slip of an active slip system is propotional to the Schmid factor of the slip system was applied to calculate the R value of an orientation. A large strain at 0˚, 90˚, 180˚, 270˚ to the RD on the 4-fold ear was explained by (0˚, 10˚, 0˚) preferred orientation in the texture. A large strain on the 6-fold ear was explained by the development of the orientations near {111}〈110〉. |
