Modeling and Simulation of Texture Evolution During the Thermomechanical Processing of Titanium Alloys (PREPRINT)

Abstract

The 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. 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.
