“…In the as-received microstructure, the c-axis of α phase are about 40°to the rolling direction and 50°t o the normal direction, and the β phase exhibits an approximate {001} < 100 > texture component, Figure 8a. After annealing, the main features of the textures of both α and β phases are completely different with that in as-received microstructure, Figure 8b-e. For α phase, a peculiarity of (0001) basal texture that nearly all c-axes are parallel to the normal direction is exhibited in the early annealing stages (1 h), Figure 8b, which is consistent with the typical rolling texture [30]. After annealing for 2 h, the (0001) basal texture in α phase weakens, Figure 8c.…”

A homogeneous equiaxed‐structure TC21 titanium alloy is hot rolled and annealed for different time ranging from 1 h to 6 h. The grain morphology and texture evolution of α and β phases during annealing are mainly investigated using the electron back‐scattered diffraction characterization. In the early annealing stage, the α grain mainly maintains the elongated morphology generated in the rolling. With increasing annealing time, more and more elongated α grains become equiaxed due to enhanced static recrystallization and boundary splitting. Differently, the β grain exhibits a fully equiaxed morphology all the time due to the sufficient static recrystallization, and get a coarsening with increasing annealing time. The α phase exhibits a (0001) basal texture in the early annealing stage, and then forms a TD‐split texture with increasing annealing time. The β phase exhibits the {001}<110> texture at every annealing time. Based on the analysis about the texture of different grain sizes, the effects of recrystallization nucleation and oriented growth on texture evolution are discussed. It suggests that TD‐split texture in α phase is originated from both the recrystallization nucleation and oriented growth. The formation of {001}<110> texture in β phase is mainly originated from the oriented growth.

“…Some believe that there is no effect of one phase on the evolution of texture in the other phase, while others believe that there is a significant effect due to presence of interface, which can affect the dislocation motion and, consequently, grain rotations. [23,24,62] The basis for the former belief is Taylor simulations considering ferrite separately, which produced a good match with the experimental ferrite texture. During cold rolling, grains fragment and tend to rotate to their stable end orientations.…”

In the present study, microstructure and texture evolution during cold rolling in UNS S32205 and UNS S32760 duplex stainless steel was investigated. Both steels were unidirectionally cold rolled up to 80 pct thickness reduction. Scanning electron microscopy and electron backscattered diffraction (EBSD) were used for microstructural characterization, while X-ray diffraction (XRD) was used for the measurement of bulk texture. Strain-induced martensite (SIM) was identified and quantified with the help of magnetic measurements (B-H curve and magnetization saturation). With the increase in plastic strain, the grains became morphologically elongated along the rolling direction with the reduction in average band thickness and band spacing. SIM increased with the increase in deformation and was found to be a function of strain and the SFE of austenite. The increase in SIM was much more pronounced in UNS S32205 steel as compared to UNS S32760 steel. After cold rolling, strong a-fiber (RD//h110i) texture was developed in ferrite, while brass texture was dominant in austenite for both steels. The strength of texture components and fibers was stronger in UNS S32760 steel. Another significant feature was the development of weak c-fiber (ND//h111i) in UNS S32760 steel at intermediate deformation.

“…Grain boundary misorientation maps on ECAP and after post-ECAP annealing from 473 -1373 K are represented in Figure 1. High angle grain boundaries (HAGB) fraction on ECAP processed microstructure is predominant with a little fraction of low angle grain boundary (LAGB) [19]. Because of low orientation resolution, boundaries with misorientation smaller than 2 was omitted.…”

The grain growth of an ultrafine-grained iron-chromium alloy has been investigated focusing on the early stage of restoration of strain. Ultrafine-grained (UFG) material has been prepared by equal channel angular pressing (ECAP) up to eight passes via route Bc. The post-ECAP annealing process was completed from 473 until 1373 K for one hour. The microstructure and hardness were then analyzed by electron back-scattering diffraction, transmission electron microscope, X-ray diffractometer and microhardness. The hardness after post-ECAP annealing exhibited the typical three-stages softening. Namely, the hardness remained stable after the annealing temperature up to 698 K and then declined significantly until the temperature of 973 K. Finally, hardness remained stable again at a higher temperature. In the second stage, grains grew uniformly, which differ from the typical nucleation-and-growth mode of discontinuous recrystallization. It was found by X-ray line broadening analysis that strain was released in the early stage prior to the significant softening stage. It was suggested that the homogeneous grain growth was led by the uniform grain distribution with a high angle grain boundaries fraction.
