摘要: The crystallographic orientation of equiaxed primary alpha (alpha p) phase is one of the main factors that determine the final texture/microtexture and mechanical properties for near-alpha titanium alloys. By annealing a forged Ti60 alloy pancake at 1030 and 1040 degrees C in the alpha+beta two-phase field, two homogeneous bimodal microstructures were obtained, the intensity of secondary alpha in the (0001) pole figure increasing with the annealing temperature. In this study, the influence of annealing temperature on the crystallographic orientation evolution in the pancake was studied using an electron backscattered diffraction analysis method. In particular, a misorientation angle theta associated with (beta Delta J beta(BOR)) that could quantitatively evaluate the deviation of the orientation relationship (OR) between alpha(p) and the surrounding 13 grains from Burgers OR was used to understand the role of the alpha(p) phase, which is considered as an anisotropic precipitate, in the texture evolution during annealing in the two-phase field. It was found that the alpha(p) grains with small theta are more readily preserved during the annealing, while their pinning effect is relatively small, resulting in faster growth of the neighboring 13 grains. A possible effect of heterogeneous local orientation distribution on the microstructure during the annealing process is also discussed. (C) 2017 Acta Materialia Inc. Published by Elsevier Ltd.
