Abstract

In this work, a 1600 tons forging machine was employed to conduct forging on the Ti-6Al-4V alloy. The microstructural and textural evolution of forged alloy were investigated by optical microscopy (OM), scanning electron microscopy (SEM), electron backscattered diffraction technique (EBSD) and X-ray diffraction (XRD). The results showed that the lamellar α phase in the Ti-6Al-4V alloy changed into a spherical morphology, and the spheroidization rate and the structure uniformity increased with the increasing forging times. The largest pole density in each incomplete pole figure of the α phase decreased gradually and the high-angle grain boundaries (HAGBs) gradually turned to the low-angle grain boundaries (LAGBs), which indicated that the texture was reduced during the forging process.
