摘要	A heterogeneous microstructure was found in a compressed near-α titanium alloy with a bimodal microstructure. The effect of the local texture on microstructural morphology was analyzed by electron backscattering diffraction techniques. Advanced orientation data processing was performed to study the micro-texture of primary α (αp) and β. The results show that there is a close relationship between local microstructure heterogeneity and local texture. The deviation angle θ can be used to quantitatively evaluate the orientation relationship (OR) between αp and the surrounding β grains from Burgers OR. The fractions of the αp/β boundary with small θ are always higher in the regions where coarse β grains exist than in the regions where the β grain is completely recrystallized. The orientation relationship between αp and β affects the recrystallization of prior β during deformation; it also exerts effects on the morphology of the transformed α phase by variant selection.
