Description This paper discusses the evolution of texture in a Ti-5Ta-1.8Nb alloy during the transformation of 'deformed alpha + beta -> alpha + beta', characterized using X-ray diffraction and Electron Back Scattered Diffraction techniques. It exhibited a deformation texture of type-[ 10 - 10]//axial direction (AD) for the wire, and a [0 0 0 2]//normal direction (ND) for the cold rolled sheet sample. On subsequent beta-homogenization treatment and cooling, the initial deformation texture was replaced with a transformation texture of [11 -20]//ND for the sheet sample. The wire sample exhibited a transformation texture with (11 -22) aligned near to the wire cross-section. A deformation texture was found to be essential to introduce transformation texture.
