Sahoo, Sanjay Kumar and Pal , Siddharth (2013) Recrystallization Texture Development in CP-Titanium. BTech thesis.
Most of the structural components are subjected to annealing as a final forming operation for different applications. It is therefore very important to understand/know the texture development during annealing of a material. This will decide the mechanical property of the component. Annealing texture of cubic crystal system has been widely researched, but little work has been done for the hexagonal close-packing materials. In the present study recrystallization texture development in CP-titanium was investigated. CP-titanium plates were subjected to cold rolling of 90% reduction in thickness. The rolled samples were then subjected to isochronal annealing at 5000C, 6000C and 7000C for 30minutes to obtain the recrystallization temperature, determined by EBSD analysis. Final annealing was carried out at 600oC for different soaking time: 10sec, 20sec, 1min, 2min, 5min, 10min, 20min and 30min to establish the texture development during annealing. These annealed samples were subsequently characterized under XRD (X-ray Diffraction) for bulk texture measurement. The initial deformation texture i.e. (1 1 -2 4)<1 -1 0 0> got attenuated with time and development of new basal orientation i.e. (0 0 0 1)<1 -1 0 0> and non-basal orientations i.e. (2 1 -3 7)<1 -2- 1 0>, (3 1 -4 9)<2 -15 13 1> and (5 1 -6 15)<1 -5 4 0> were observed.
