Abstract
The macrotextures and microtextures produced during alpha + beta forging of Ti–10V–2Fe–3Al were characterised using neutron, in situ synchrotron X-ray and ex situ electron backscatter diffraction (EBSD). The EBSD analysis showed that the measured misorientation distributions at a strain of 0.8 and strain rates of 0.1 and 0.01 s^-1 were similar, with an average misorientation of 2.2°. During forging, the moderate cube macrotexture inherited from the parent material was converted into a moderate fibre texture, with the major change occurring between strains of 0.4 and 0.6. The synchrotron diffraction studies allowed the orientation evolution of individual grains to be characterised. At the highest strain rate of 0.1 s^-1, this indicated a change in behaviour from dispersion of the crystal mosaic (peak angular spread) at low strains, to convergence of the crystal mosaic at larger strains. At lower strain rates, only convergence of the crystal mosaic was observed. It is suggested that these results indicate a change in mechanism between deformation-controlled behaviour during the early stages of deformation and a strain rate of 0.1 s^-1 and diffusional, recovery-controlled behaviour at lower strain rates and higher strains.
