Formation of a (001) [100] deformation structure in aluminum single crystals of an S-orientation

Effect of Initial Grain Size on the Evolution of {001}〈100〉 Texture in Severely Deformed and Annealed High-Purity Nickel

“…Nucleation of off-cube and randomly oriented grains in the shear-banded regions has also been reported by other authors in different materials. [15,16] Although the high orientation gradient and finer structure associated with shear bands offers a favorable environment for early nucleation, the propagation of shear bands is generally considered detrimental for the development of cube texture. Ridha and Hutchinson [10] argued that the propagation of shear bands may break the elongated cube bands into shorter lengths and destroy the native structure of the cube bands favorable for their early nucleation.…”

Evolution of Deformation and Recrystallization Textures in High-Purity Ni and the Ni-5 at. pct W Alloy

“…This is a result of the nucleation of noncube or even random orientations in the shear banded regions in the process of recrystallization. [14,25,26] Clear evidence of nucleation of noncube-oriented grains has been reported in the locally sheared regions in this alloy. [27] However, the volume of sheared material either is limited, or sometimes the shear bands are not so well developed as observed in the current case.…”

In-situ annealing and computation study of cube texture development in a commercial aluminum alloy

“…In many cases the cube component is seriously underestimated which gives rise to the supposition that there are cube nucleation sites besides the well-known cube bands. Indeed, a detailed pole figure analysis of heavily deformed aluminum single crystals [19,20] indicated that the S-orientation may eventually rotate into the cube orientation and thus provide recrystallization nuclei with cube orientation. Also, deformation simulations with the crystal plasticity finite element method (CPFEM) of a grain assembly comprising symmetrically equivalent Sorientations indicated the development a of cube oriented volume at the grain boundaries [21].…”

“…Dillamore and Katoh explained the formation of the cube orientation in terms of transition bands formed due to divergent lattice rotations of cube oriented grains caused by different combinations of slip systems [18]. Kamijo et al reported the formation of a {001}<100> orientation during rolling of an aluminum single crystal with S-orientation and the importance of such regions for the nucleation of cube RX grains [19,20]. Their findings were supported by finite-element model (FEM) simulations of Beaudoin et al [21], who found that orientations close to cube would develop in highly strained regions where complimentary S-orientations meet.…”
