“…21) All these results are not expected because in a pure Cu sheet after cold rolling, the copper-type rather than the brass-type textures are reported to be the dominant texture components. 14,33) Recent investigations by both experiments, 18,19,34) and numerical simulations 23,35) have shown that in single-phase fcc materials under large deformations, shear banding leads to the strengthening of the brass-type textures, and, this texture evolution is different from that induced by dislocation slip and twinning. Therefore, it is suggested that the texture evolution of the interfaceCu layer within the Cu-Ag composite is strongly influenced by the existence of the abutting Ag phase or the interface between the constituent phases.…”

The inhomogeneous texture distribution in a lamellar composite incorporating two dissimilar face-center-cubic metals, i.e., Cu and Ag, under cold rolling is investigated. When the thickness reduction is higher than 80%, the heterogeneity of textures is found in the Cu layer. Namely, in the region adjacent to the rollers the Copper component dominates over the other textures, whereas in the region closed to the heterointerface the Brass component is the dominant texture. Lattice rotations within the heterophase microstructure are then addressed by crystal plasticity finite element modeling that considers not only crystallographic (dislocation slip and twinning) but also non-crystallographic (shear banding) micromechanisms. The simulations show that the hetero-interface between the Cu and Ag layers plays an important role in texture development of the Cu layer when the two metals are co-deformed. In the Cu phase of the studied composite, significant shear banding is triggered by stress concentration at the hetero-interface compared to the positions away from the interface, which leads to the dominant Brass texture in the interface region.

“…The neutron diffraction technique is very useful because of the very small absorption of neutrons by metals, and this enables studying coarse-grained bulk samples. Using this technique absorption correction can be neglected and the possible variation of texture through the thickness of the sample can be integrated [4]. The comparison between the neutron diffraction measurements and the model predictions suggests that in most cases the finite model can predict the lattice strain evolution at the microscale and capture the general trends observed in the experiments [7].…”

“…Different microscopic mechanisms have been put forward to account for the copper-type texture (normal slip, cross slip, non-octaheral slip) and for the brass-type texture (normal slip, slip of partial dislocations, mechanical twinning [3]). Nevertheless, the problem remains still not well explained [4].…”

Austenitic steel is one type of stainless steel which is widely used in the industry. Many studies on austenitic stainless steel have been performed to determine the physical properties using various types of equipment and methods. In this study, the neutron diffraction method is used to characterize the materials which have been made from minerals extracted from the mines in Indonesia. The materials consist of a granular ferro-scrap, nickel, ferro-chrome, ferro-manganese, and ferro-silicon added with a little titanium. Characterization of the materials was carried out in three processes, namely: machining, annealing, and rolling. Experimental results obtained from the machining process generally produces a texture in the 〈100〉 direction. From the machining to annealing process, the texture index decreases from 3.0164 to 2.434. Texture strength in the machining process (BA2N sample) is 8.13 mrd and it then decreases to 6.99 in the annealing process (A2DO sample). In the annealing process the three-component texture appears, cube-on-edge type texture {110}〈001〉, cube-type texture {001}〈100〉, and brass-type {110}〈112〉. The texture is very strong leading to the direction of orientation {100}〈001〉, while the {011}〈100〉 is weaker than that of the {001}, and texture with orientation {110}〈112〉 is weak. In the annealing process stress release occurred, and this was shown by more randomly pole compared to stress release by the machining process. In the rolling process a brass-type texture{110}〈112〉 with a spread towards the goss-type texture {110}〈001〉 appeared, and the brass component is markedly reinforced compared to the undeformed state (before rolling). Moreover, the presence of an additional {110} component was observed at the center of the (110) pole figure. The pole density of three components increases with the increasing degree of thickness reduction. By increasing degrees of rolling from 81% to 87%, the value of orientation distribution function increases by a factor about three times.

“…Shear bands (SBs) or their compact clusters, called macroscopic shear bands (MSBs), are frequently observed examples of unstable behaviour of fcc metallic materials at large strains, e.g. [1][2][3][4][5][6][7][8][9][10][11][12][13][14].

Microstructure and texture development in medium-to-high stacking fault energy face centred cubic metals were investigated in order to examine the role of lattice re-orientation on slip propagation across grain boundaries and to characterize the influence of micro-and macro-scale copper-type shear bands on textural changes at large deformations. Polycrystalline pure copper (fine -and coarse -grained) and fine-grained AA1050 alloy were deformed in plane strain compression at room temperature to form two sets of well-defined macroscopic shear bands. The deformation-induced sub-structures and local changes in crystallographic orientations were investigated mostly by scanning electron microscopy equipped with high resolution electron backscattered facility. In all the deformed grains within macro-shear bands a strong tendency to strain-induced re-orientation was observed. The flat, strongly deformed grains exhibited a deflection within narrow areas. The latter increased the layers' inclination with respect to ED and led to kink-type bands, which are the precursors of MSBs. The mechanism of macro-/ micro-shear bands formation is strictly crystallographic since in all the areas of the sheared zone, the crystal lattice rotated such that one of the {111} slip planes became nearly parallel to the shear plane and the <011> direction became parallel to the direction of maximum shear. This strain-induced crystal lattice rotation led to the formation of specific macro-/ micro-shear bands components that facilitated slip propagation across the grain boundaries without any visible variation in the slip direction.Keywords: Shear bands, Texture, SEM/EBSD, Copper, AA1050 alloy, Plane strain compression W pracy badano zmiany strukturalne i teksturowe w metalach o sieci regularnej ściennie centrowanej związane z lokalną re--orientacją sieci krystalicznej wynikającą z formowania się mikro-i makro-pasm ścinania. Analizowano polikrystaliczne próbki miedzi oraz aluminium o czystości technicznej (stop AA1050) odkształcane w temperaturze otoczenia w próbie nieswobodnego ściskania do zakresu odkształceń, w których następuje wyraźne uformowanie się dwóch rodzin makroskopowych pasm ścinania. W badaniach wykorzystano skaningowy mikroskop elektronowy wyposażony w system automatycznego pomiaru orientacji lokalnych. Zaobserwowano, że w ziarnach umiejscowionych w obszarze makroskopowych pasm ścinania występuje ściśle zdefiniowana tendencja rotacji sieci krystalicznej, w wyniku której jedna z płaszczyzn typu {111} przyjmuje położenie zbliżone do położenia płaszczyzny ścinania, a jeden z kierunków typu <110> (lub <112> ) wykazuje tendencję do sytuowania się równolegle do kierunku ścinania. Obserwowana w obszarze wnętrza pasm ścinania rotacja prowadzi do uformowania się specyficznej (mikro)tekstury, która umożliwia propagację poślizgów poprzez granice ziaren bez 'istotnej' zmiany kierunku ścinania.
