摘要	The room temperature deformation behaviors of Ti-6Al-4V were investigated using crystal plasticity (CP) simulations to analyze the influence of texture on the mechanical and micromechanical properties of the alloy. The equiaxed microstructure with four different textures, namely random, basal, basal/transverse, and transverse, were generated using Dream 3D software. The alloy with random texture was used to study the influence of basal and prism critical resolved shear stress (CRSS) on the alloy properties. The findings revealed that the strength of the alloy is more sensitive to an increase in basal CRSS, whereas an increase in prism CRSS significantly affects plasticity. The analysis of microstructural stress and strain showed that the hard alpha grains accommodate the majority of the stress in the microstructure, while the soft alpha and beta grains accommodate plastic strain. The simulations indicated that the basal texture exhibits the lowest strength and twin fractions, the basal/ transverse texture displays intermediate strength, and the transverse texture has the highest strength along both the rolling direction (RD) and transverse direction (TD), accompanied by the highest twin fractions along TD. The alloy showed the highest strength when loaded along TD, parallel to the c-axes of the most frequently occurring grains, while the lowest strength was observed when loaded along RD, perpendicular to the c-axes of the most frequent grains. Under both tension and compression, the highest twin fractions were observed along TD, followed by RD, and then the through-thickness (TT). This research provides valuable insights into the mechanical and deformation mechanisms of titanium alloys under common textures.
