“…2c). In agreement with findings in the literature [3][4][5][6][7][8][9][10]17,18], twinning seemed to be suppressed at this level of reduction. In addition, the twin boundaries were almost completely transformed into HABs with misorientations different from those associated with twinning (Fig.…”

“…Microstructure evolution at relatively low and intermediate strains (r75%) was found to be in good agreement with prior observations [3][4][5][6][7][8][9][10]. At low strains, microstructure evolution was dominated by the development of f1122g〈112 3〉 compressive and f1012g〈101 1〉 tensile twins which rapidly refined the grain size.…”

“…6b and c). This is also an expected result [6][7][8][9][10]; this texture is believed to be stable during rolling and originates from a balance between twinning, prism slip, and 〈c þa〉 slip [9]. Formation of this texture is thought to contribute (at least partially) to the rapid drop of the strain hardening rate observed in this strain range (Fig.…”

“…At relatively large thickness reductions (Z40%), grain refinement suppresses twinning activity, and slip becomes the dominant deformation mode [9,10]. Microstructure formation at these large strains has been hypothesized to be largely controlled by the development of deformation-induced dislocation boundaries [5,8], but the details of this process are not clear.…”

a b s t r a c tHigh-resolution electron back-scatter diffraction (EBSD) analysis was employed to establish mircostructure evolution in heavily cold-rolled alpha-titanium. After thickness reductions of 75% to 96%, significant microstructure and texture changes were documented. The surface area of high-angle grain boundaries was almost tripled, thus giving rise to an ultra-fine microstructure with a mean grain size of 0.6 μm. Moreover, orientation spread around typical 'split-basal' rolling texture substantially increased.These effects were suggested to be related to the enhancement of pyramidal 〈c þa〉 slip.

Managing the metal's texture throughout the entire processing procedure is imperative for controlling the final properties of metal alloys. In the aerospace industry, α‐Ti alloys have been successfully utilized in applications such as aircraft skins, heat shields, and heat exchangers. However, inherent mechanical strength, fatigue sensitivity, and fracture toughness limitations have significantly restricted their wider adoption. On the other hand, β‐Ti alloys have received increasing attention in the biomedical field due to their lower elastic modulus. However, their actual application has been primarily restricted by the inability to match natural bone's Young's modulus sufficiently. Among these application limitations for both α‐Ti and β‐Ti alloys, texture is an essential factor affecting mechanical properties. Elucidating texture evolution on α‐Ti and β‐Ti alloys is crucial for enabling the expansion of their applications. This review summarizes detailed analyses of the intertwined evolution of texture and microstructure in α‐Ti and β‐Ti alloys during cold rolling, hot rolling, and annealing. Furthermore, based on these fundamental materials science insights, the resultant impact of texture and microstructure on achieving targeted mechanical properties is discussed. Finally, potential pathways are proposed to further guide texture and microstructure evolution in α‐Ti and β‐Ti alloys to meet application requirements.

Residual strain and texture variations were measured in two titanium matrix composites reinforced with silicon carbide fibers (Ti/SiC) of similar composition but fabricated by different processing routes. Each composite comprised a Ti-6242 ␣/␤ matrix alloy containing vol 35 pct continuous SiC fibers. In one, the matrix was produced by a plasma sprayed (PS) route, and in the other by a wiredrawn (WD) process. The PS and WD composites were reinforced with SCS-6 (SiC) and Trimarc (SiC) fibers, respectively. The texture in the titanium matrices differed significantly. The titanium matrix for the PS material exhibited random texture pre and post fabrication of the composite. For the WD material, the starting texture of the monolithic titanium matrix was Ϸ17 times random, but after consolidation into composite form, it was Ϸ6 times random. No significant differences were noted in the fiber-induced matrix residual strains between the composites prepared by the two procedures. However, the Trimarc (WD) fibers recorded higher (Ϸ1.3 times) compressive strains than the SCS-6 (PS) fibers. Stresses and stress balance results are reported. Plane-specific elastic moduli, measured in load tests on the unreinforced matrices, showed little difference.
