Mechanical Properties, Deformation Textures, Elastoplastic Behaviour of BCC Polycrystalline Materials

Abstract

A certain number of uniaxial tensile tests have been performed as well along the rolling and transverse directions as out of the principal axes of anisotropy in a low carbon rimmed steel sheet with equiaxed grains. The deformation textures and the Lankford’s ratio are calculated for these loading pathes in the framework of different Taylor's type models generalized to all the classes of symmetry allowed for the texture even though the previous works only be focused on the orthotropic symmetry. Different glide assumptions ( {110}<111> crystallographic slip, {110}<111> + {112}<111> mixed conditions, pencil glide) are explored. Furthermore some models are applied to the calculation of the deformation textures obtained during the rolling process.
