The near-β titanium alloy. Ti-10V-2Fe-3Al (Ti-10-2-3), is often isothermally forged at 760 °C for aircraft landing gear applications. The microstructural development of this alloy has received much attention but the macrotextures and microtextures that evolve during forging have not been investigated to any great extent.The EBSD technique was used to determine the misorientation distributions between the subgrains at a strain of 0.8 and strain rates of 0.1 and 0.01 s~(-1). The measured distributions were found to be similar, with an average misorientation of 2.2°.Time of fight neutron diffraction allowed the macrotexture evolution to be studied. Interrupted testing was performed at 0.01 s~(-1) to a strain of 0.2, 0.4. and 0.6 and 0.8. It showed that the moderate cube macrotexture inherited from the parent material was converted into a moderate fibre texture. The major change occurred between strains of 0.4 and 0.6.The in situ synchrotron diffraction studies allowed the orientation evolution of individual grains to be characterised. For 0.1 s~(-1) a change in behaviour from dispersion of the crystal mosaic at low strains to convergence of the crystal mosaic at larger strains was observed. At lower strain rates, only convergence of the crystal mosaic was observed. These results appear to 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 lower strain rates and higher strains.
