Abstract
Stability of ideal orientations and texture formation during deep drawing were investigated for a hot roiled AA 1050. Lattice rotation fields around ideal orientations were numericlly predicted using a rate sensitive polycrystal model with full constraint boundary conditions. In order to evaluate the strain path during deep drawing of an AA1050, simulations using a finite element analysis were carried out. The stability of orientations and texture formation were examined at the sequential strain paths such as flange deformation and wall deformation. During flange deformation, Goss and Pf 0 1 1 (shifted form P {0 1 1} ) satisfied the stability condition of texture formation, while during wall deformation, only Bw {0 1 1} (shifted from Brass) and Dw {5 5 12} (shifted from Dillamore) satisfied the stability condition of orientation.
