SIMULATION OF THE DEFORMATION TEXTURES INDUCED BY DEEP-DRAWING IN EXTRA LOW-CARBON STEEL SHEETS

Predictions were made of the texture changes that are expected to take place during the deep drawing of extra low carbon IF steels. The simulations were carried out using a rate dependent theory for mixed {112}- and {110}[111] slip. Three grain interaction models were employed, based on the full constraint (FC), relaxed constraint (RC) and least work (LW) theories. It is shown that the experimentally observed grain reorientations are reproduced reasonably well using the full contraint and least work models. The orientation dependences of the preferred deformation modes are described, together with the relative stabilities of the expected end textures.
