“…The development of recrystallisation textures in a commercially pure cold rolled titanium sheet has been studied by several investigators in detail [23][24][25]27,29,33,34,41,49,56,57 . The results of these studies clearly indicate that the recrystallisation texture of cold rolled titanium sheet strongly depends on the annealing temperature in the α phase field.…”

“…This texture was visualized as the combination of the 〈10.0〉 tension texture and rotated <00.1> compression texture. Texture studies by pole figure measurement of pure titanium 16,[20][21][22][23][24][25][26]40 exhibit basal poles which tend to concentrate in the regions ±(0 to 40°) from the rolling plane in the rolling direction at low strains (< 20% reduction). On further rolling reduction to a strain of 40%, this pole splits along the rolling direction, then rapidly disappears and finally a new split in the transverse direction emerges.…”

“…Hot rolling textures of pure titanium have been studied by only a few investigators [11][12][13][14][15] . All these investigations have been made by using the X-ray diffraction (XRD) pole figure method only and have identified main orientations of the hot rolled titanium in terms of {0002} pole figures.…”

TP 2233properties are strongly influenced by the texture present in the alloy. The evolution of textures in these alloys originates by a combination of deformation, recrystallisation and phase transformation during processing. In general, the evolution of texture in titanium and its alloys depends mainly on: (i) the mode of deformation (rolling, forging and extrusion), (ii) the starting texture and microstructure, (iii) temperature and rate of deformation, (iv) the total reduction and (v) the alloying elements. The purpose of this article is to provide a comprehensive and coordinated review of the evolution of texture and its influence on mechanical properties of titanium and its alloys. An attempt has also been made to discuss the possible mechanisms of the evolution of texture, variant selection during phase tranformations and deformation behavior of these alloys. CRYSTAL STRUCTURES AND CLASSIFICATION OF TITANIUM ALLOYSPure titanium appears in two allotropic forms: low temperature α titanium with cph structure and high temperature (>882°C) ABSTRACTThe purpose of this article is to provide a comprehensive and coordinated review of the evolution of texture during thermomechanical processing of titanium and its alloys. In general, the evolution of texture depends on several factors such as deformation temperature, mode of deformation (rolling, forging and extrusion), initial texture and microstructure, degree and rate of deformation and alloying elements. Phase transformation textures and associated variant selection mechanisms as function of initial texture and heat treatment have also been discussed. The chronological developments of texture modelling and deformation mechanisms in these alloys are presented.

“…[15] Recrystallization of titanium and zirconium at low temperatures produces a texture in which the [11 0] direction is parallel to 2 the deformation axis with all the azimuthal positions possible for the [0001] direction. For titanium, it has been shown that the majority of the basal planes are tilted 11 deg to the deformation axis.…”

“…[15][16][17][18] At very low annealing temperatures, the recrystallization texture is the same as the deformation texture; however, at higher annealing temperatures, there could be a lattice reorientation as a result of high-angle grain boundary motion. The annealing texture of hafnium also showed a very strong temperature dependence.…”

This article presents a study of the evolution of the annealing texture in hafnium, as measured by electron backscattering diffraction patterns (EBSPs). It was found that the annealing texture of asreceived extruded rod depended on the annealing temperature. After low-temperature recrystallization, the deformation axis was parallel to [11 0] or [ 2 0] and the basal planes were approximately 2 1 1 parallel to the deformation axis. These orientations were deduced by the position of the points in the standard stereographic triangle used to produce the inverse pole figure. As the annealing temperature was raised to 1700 ЊC, the direction parallel to the rolling direction changed to [01 0] and 1 the grain size increased. It appeared that the increase in grain size occurred by a process of abnormal grain growth, and this abnormal grain growth appeared to be the cause of the change in the texture. Texture was also examined in samples that had been warm rolled to thickness reductions between 10 and 90 pct and then annealed at 1700 ЊC. In these samples, the main feature of the texture was that the basal plane became parallel to the rolling plane as the amount of rolling increased. The maximum grain size was observed in samples that had been rolled to a reduction in thickness of 50 pct.
