Abstract

The variation of microstructure and microtexture across a Ti-6Al-4V (Ti64) linear friction weld was investigated using scanning electron microscopy (SEM) and electron backscattered diffraction (EBSD). Pole figures and misorientations distribution obtained from α phase show four distinct regions within the weld, with different textural characteristics. Nevertheless, the main texture components remain the same in centre weld zone and thermal mechanical affected zone with the basal poles of the α phases located at around 0°, 60° and 90° to the sample normal (Z0) direction. The results indicate that the texture components are strongly related to the amount of transformed β phase. The deformation of the primary α grains has a limited effect on the texture development.
