| Abstract |
Deformation by rolling induces in general a strong crystallographic texture, hence an
important material anisotropy. This is a reason why the cross-rolling is sometimes applied in order
to symmetrize the crystallographic texture. Such an operation modifies also residual stresses. The
goal of this study was to characterize residual stress and texture changes during simple and crossrolling
in polycrystalline copper and ferritic steel. The obtained results show that important
modification of the first order residual stresses occurs during cross-rolling, while the level of the
second order ones is approximately constant. Experimental results were analysed using an elastoplastic
deformation model. |
