“…In similar work, Ma and his coworkers [31,32] simulated texture-controlled grain growth during beta annealing of Ti-6Al-4V using the phase-field method. The effect of 14 grain-boundary energy/mobility and specific type of initial texture on grain-growth kinetics and the evolution of the different texture components were evaluated.…”

ABSTRACTThe development of crystallographic texture, the preferred orientation of grains in a polycrystalline aggregate, during thermomechanical processing (TMP) can play an important role with regard to the secondary-forming response (e.g., deep drawing of sheet) and service performance (e.g., strength, elastic modulus, ductility, fracture toughness) of metallic materials. Crystallographic texture, or simply texture for succinctness, may arise as a result of large-strain deformation, dynamic/static recrystallization, grain growth, or phase transformation [1]. A second form of anisotropy, mechanical texturing or mechanical fibering, refers to the alignment of microstructure, inclusions, etc., during deformation processes and may also affect mechanical properties such as ductility and fracture toughness. This latter form of texture is not discussed in the present article.

“…Such texture-controlled grain growth is a result of the anisotropy in energy and mobility of beta grain boundaries, whose effects have been quantified using deterministic, Monte-Carlo, and phase-field simulation methods. [7][8][9][10][11] Phenomenological measurements and modeling research on beta grain growth have been complemented by investigations which have shed light on the relation between the beta-phase texture developed during subtransus processing and that which evolves during annealing in the single-phase beta field. For example, Moustahfid, Divinski, and their coworkers [12,13] were perhaps the first to demonstrate that the beta-phase texture developed during beta annealing contains components that were present during subtransus processing.…”

The early stages of microstructure evolution during annealing of Ti-6Al-4V in the beta phase field were established. For this purpose, a series of short-time heat treatments was performed using sheet samples that had a noticeable degree of alpha-phase microtexture in the as-received condition. Reconstruction of the beta-grain structure from electron-backscatter-diffraction measurements of the room-temperature alpha-phase texture revealed that microstructure evolution at short times was controlled not by general grain growth, but rather by nucleation-and-growth events analogous to discontinuous recrystallization. The nuclei comprised a small subset of beta grains that were highly misoriented relative to those comprising the principal texture component of the beta matrix. From a quantitative standpoint, the transformation kinetics were characterized by an Avrami exponent of approximately unity, thus suggestive of metadynamic recrystallization. The recrystallization process led to the weakening and eventual elimination of the initial beta texture through the growth of a population of highly misoriented grains.
