Etude de l'évolution de la texture cristallographique d'acier extra-doux au cours du tréfilage et d'une opération particulière de laminage : détermination des contraintes internes

Abstract : The aim of yhis work is to determine the influence which the texture of the material in the case of the IFS and Al-killed steels may have on the drawability limit according to different drawing and metallurgical conditions. A study of the texture during a specific cold rolled process has also been carried out to compare the obtained textures with two different deformation processes. Since any plastic deformation introduces residual stresses in the material, it was necessary to quantify them in order to predict the in-use behaviour of the material. These residual stresses by means of X-ray diffraction have been determined by taking the crystallographic texture into account
