“…[48,49] The {111}<110> texture is a dominant deformation texture. [48][49][50][51][52] As the rolling reduction is enhanced from 30% to 70%, rotation from the {111}<112> texture to the {111}<110> texture occurs during cold-rolling deformation, which results in an increase in the intensity of the {111}<110> texture and a decrease in the intensity of the {111}<112> texture (Figure 8c-e). For the {001}<110> and {001}<100> textures, Figure 9 shows that the volume fractions of the {001}<110> and {001}<100> textures are almost unchanged when enhancing the rolling reduction from 10% to 70%.…”

The microstructure, texture evolution, and aging behavior of a cold‐rolled (CR) Ti–B20 alloy are investigated in this work. The results show that the microstructure of the solution‐treated (ST) Ti–B20 alloy consists of equiaxed recrystallized grains and exhibits typical {001}<110> and {001}<100> textures. After cold rolling, the initial equiaxial grains are stretched along the rolling direction (RD), which can produce typical deformation textures of γ‐fiber {111}<112> and {111}<110> textures. For the CR samples after aging treatment, small amounts of needle‐like or spherical α‐phases preferentially precipitate in the grain boundaries of deformed β grains during aging treatment; many nanosized α‐phases uniformly precipitate in the grain boundaries and inside the β grains. A high dislocation density is generated in CR samples, promoting α‐phase nucleation, increasing the volume fraction, and decreasing the α‐phase size during aging treatment.

“…It is seen that the texture component was mainly made up of {001}<100>, {011}<100>, {110}<112>, and {112}<110> textures. For the body-centered cubic (BCC) alloys, the {001}<100> and {011}<100> textures are considered to be a typical recrystallization texture, whereas the {112}<110> and {110}<112> textures are the dominant deformation textures [10,27,[30][31][32][33][34][35][36]. It is shown in Figure 13a,b that the volume fraction of the {001}<100> texture rapidly rose with the reduction in strain rate and increase in hot-deformation temperature.…”

The effect of hot working parameters on the microstructure and texture evolution of the hot-deformed Zr-45Ti-5Al-3V alloy was studied by the electron backscatter diffraction (EBSD) technique. It was found that a high density of dislocations were generated when the alloy was deformed at 700 °C/0.001 s−1 and 800 °C/1 s−1. With the increment in hot-deformation temperature and the decrease in strain rate, the dislocation density decreased due to the increase in dynamic recrystallization (DRX) degree. The discontinuous dynamic recrystallization (DDRX) and continuous dynamic recrystallization (CDRX) mechanisms co-existed during the hot working of the Zr-45Ti-5Al-3V alloy at a true strain of 0.7. The texture evolution of the alloy during hot working was characterized and the texture component mainly consisted of {001}<100>, {011}<100>, {110}<112>, and {112}<110> textures. The volume fractions of {001}<100> and {011}<100> textures obviously rose with the reduction in strain rate, whereas those of {110}<112> and {112}<110> textures gradually decreased. At a given strain rate, an increase trend in the volume fraction of the {001}<100> texture was observed with rising hot-deformation temperature, while the volume fraction of the {011}<100> texture first increased and then decreased. An opposite trend was visible in the {112}<110> and {110}<112> texture compared with {011}<100> textures.

Texture and Microstructure Evolution of Ultra-High Purity Cu-0.1Al Alloy under Different Rolling Methods

et al. 2021

The microstructure and texture distribution of ultra-high purity Cu-0.1Al alloy target play a key role in the quality of the sputtering film. The Cu-0.1Al alloy sheets were processed by unidirectional (UR) and cross rolling (CR), and X-ray diffraction (XRD), and electron backscatter diffraction (EBSD) technologies were adopted to observe the texture and microstructure evolution. XRD results reveal that the texture types vary greatly in UR and CR due to the change of strain path. As the strain increases to 90%, S texture occupies the most, followed by copper texture in the UR sample, while brass texture dominates the most in the CR sample. Additionally, the orientation density of texture does not increase significantly with the increase of strain but shows a downward trend both in UR and CR modes. EBSD analysis demonstrates that compared with UR, the deformation microstructure in CR is more uniform, and the layer spacing between the deformation bands is smaller, which can reduce the local-region stress concentration. After the completion of recrystallization, the difference in average grain size between the UR and CR-annealed samples is not significant, and the recrystallized grains become much finer with the increase of strain, while more equiaxed grains can be observed in CR-annealed samples.
