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.

“…In most cases, it is not necessary to distinguish between an annealed and a cold-worked texture since m;my properties are symmetrical about the c axis. Thus, a basal-pole figure is sufficient to define the crystallographic influ•mce, and the above texture can be modified by either hot ro'ling [56] (above 1400 F but not above beta transus) and 'or alloying. Important observations in relation to texture strengthening were that additions of approximately 4 percent aluminum [45,46] (an early discovery) and approximately 0.5 percent copper (the most recent disclosure: produce the "ideal" texture.…”
