Shear deformation is imposed on materials by several advanced techniques for microstructural and textural control. Shear texture evolved during deformation tends to remain after subsequent annealing. Texture evolutions with shear deformation and subsequent annealing in aluminum and Al-3mass%Mg alloy rolled sheets have been investigated by neutron diffraction technique. N-shaped specimen was prepared from the alloy sheet to impose shear strain in compression. The central objective part of the N-shaped specimen was sheared with slight rotation about the normal axis so as to develop preferred orientations of {111} parallel to the original shear plane and parallel to the original shear direction before deformation. In-situ neutron diffraction analysis during step heating revealed that the preferred orientations formed by shear deformation remain and evolve as recrystallization texture during subsequent annealing in both materials. Evolutions of shear and recrystallization textures were compared after shear deformations with strains of 0.5 and 0.7 in two samples sheared parallel to rolling and transverse directions.
