Texture Evolution of α‐Ti and β‐Ti Alloys During Rolling and Recrystallization

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.
