The evolution of the alpha- and beta-phase textures during processing of a 760-mm diameter production-scale VAR Ti-6Al-4V ingot into a 153-mm thick billet was established using orientation-imaging microscopy, x-ray pole-figure measurements, and a novel real-time Laue mapping system. For this purpose, alpha-phase textures were determined directly from specimens cut from corresponding regions of ingot and billet cross sections. To determine the texture of the beta phase, two separate techniques were employed. The first method used the measured orientations of alpha-phase variants from a number of prior-beta grains that had been indexed using an orientation-imaging microscope and a special analysis based on the burgers relation between the alpha and beta phases. The second approach involved direct measurement of the beta-phase texture using x-ray diffraction techniques. The results of this work established that distinct textures in both phases were developed at each stage of the thermomechanical processing sequence. Moreover, at specific stages of the processing sequence, the textures of both phases varied and were found to be spatially inhomogeneous.
