“…A light etched area with deformation bands and a dark etched area with internal shear bands were identified in all the samples. The deformation stored The above results indicate that hot rolling significantly weakens the {100} texture in the as-cast strip, which is different from the effect of cold rolling reported in a previous study [32]. It is likely that {100} was enhanced in the case of direct cold rolling due to the formation of new Cube deformation bands in the {115}<051>-{115}<161> grains [32].…”

In this study, the effect of the hot-cold rolling process on the evolution of the microstructure, texture and magnetic properties of strip-cast non-oriented electrical steel was investigated by introducing hot rolling with different reductions. The results indicate that hot rolling with an appropriate reduction, such as the 20% used in this study, increases the shear bands and {100} deformed microstructure in the cold roll sheet. As a result, in our study, enhanced η and Cube recrystallization texture and the improved magnetic induction were obtained. However, hot rolling with excessive reduction (36–52%) decreased the shear bands and increased the α-oriented deformation microstructure with low stored energy. It enhanced the α recrystallization texture and weakened the η texture, resulting in a decrease in the magnetic induction. In addition, hot rolling promoted the precipitation of supersaturated solid solution elements in the as-cast strip, thereby affecting the subsequent microstructure evolution and the optimization of its magnetic properties.

“…In summary, the Goss and Cube textures had a higher nucleation rate at the shear band of the extruded aluminum alloy, resulting in the nucleation of Goss and Cube textures dominating the early stage of recrystallization. With the progress in recrystallization, several new grains with random orientation were formed in the microstructure [44,45]. The schematic diagram of the relationship between the orientation of textures: Copper, G/B T , Goss and Cube textures and the macroscopic orientation of samples is shown in Figure 3b.…”

High-performance extruded aluminum alloys with complex textures suffer significant dimension variation under environmental temperature fluctuations, dramatically decreasing the precision of navigation systems. This research mainly focuses on the effect of the texture of extruded pure aluminum on its dimensional stability after various annealing processes. The result reveals that a significant increment in the area fraction of recrystallized grains with <100> orientation and a decrement in the area fraction of grains with <111> orientation were found with increasing annealing temperature. Moreover, with the annealing temperature increasing from 150 °C to 400 °C, the residual plastic strain after twelve thermal cycles with a temperature range of 120 °C was changed from −1.6 × 10−5 to −4.5 × 10−5. The large amount of equiaxed grains with <100> orientation was formed in the microstructure of the extruded pure aluminum and the average grain size was decreased during thermal cycling. The area fraction of grain with <100> crystallographic orientation of the sample annealed at 400 °C after thermal cycling was 30.9% higher than annealed at 350 °C (23.7%) or at 150 °C (18.7%). It is attributed to the increase in the proportion of recrystallization grains with <100> direction as the annealing temperature increases, provided more nucleation sites for the formation of fine equiaxed grains with <100> orientation. The main orientation of the texture was rotated from parallel to <111> to parallel to <100> after thermal cycling. The change in the orientation of grains contributed to a change in interplanar spacing, which explains the change in the dimension along the extrusion direction during thermal cycling.

“…In this regard, we can cite the well-known Goss texture for 3%siliconiron alloys [39] used as vehicles of the magnetic flux in high power transformers: the magnetic permeability in the rolling direction is greatly improved comparing to the magnetic permeability of an isotropic 3%silicon-iron polycrystal; the coercive field is considerably reduced, leading to a drastic decrease of energy losses per magnetization cycle. References [34,56,45] thus report recent developments in this field. On the other hand, cold rolled and annealed FeNi alloys are known to be able to develop a so-called cube texture during recrystallization [3,57], meaning that the crystallographic frame coincides with the sheet frame: this texture leads to a high magnetic permeability in both the rolling and transversal (to the rolling) directions.…”

The description of the behavior of a material subjected to multi-physics loadings requires the formulation of constitutive laws that usually derive from Gibbs free energies, using invariant quantities depending on the considered physics and material symmetries. On the other hand, most of crystalline materials can be described by their crystalline texture and the associated preferred directions of strong crystalline symmetry (the so-called fibers). Moreover, among the materials produced industrially, many are manufactured in the form of sheets or of thin layers. This article has for object the study of the magneto-mechanical coupling which is a function of the stress 𝜎 𝜎 𝜎 and the magnetization 𝑀 𝑀 𝑀 . We consider a material with cubic symmetry whose texture can be described by one of three fibers denoted as 𝜃, 𝛾 or 𝛼 ′ , and which is thin enough so that both the stress and the magnetization can be considered as in-plane quantities. We propose an algorithm able to derive linear relations between the 30 cubic invariants 𝐼 𝑘 of a minimal integrity basis describing a magneto-elastic problem, when they are restricted to in-plane loading conditions and for different fiber orientations. The algorithm/program output is a reduced list of invariants of cardinal 7 for the {100}-oriented 𝜃 fiber, of cardinal 15 for the {110}-oriented 𝛼 ′ fiber and of cardinal 8 for the {111}-oriented 𝛾 fiber. This reduction (compared to initial cardinal 30) can be of great help for the formulation of low-parameter macroscopic magneto-mechanical models.
