Abstract

Understanding of recrystallization texture, the objective of the present study, is very important because most of the engineering components subjected to annealing as a final forming operation before different applications. Such recrystallization texture is well established in cubic materials compared to hexagonal materials. In the present study recrystallization texture development in Ti-6Al-4V has been investigated. Ti-6Al-4V plates were subjected to rolling at 600 oC for 85% reduction in thickness. The rolled sheets were then annealedat 850 oC for different soaking time of 0.5 min, 1min, 2min, 5min, 10min, 30min, 1hr, 2hr and 5hr respectively to establish the texture development during annealing in the material. It was observed that the grain size of both and phases increased with increasing the annealing time and the samples were fully recrystallized beyond 1 hr of annealing time. A strong near basal texture was evolved in annealed samples as a function of annealing time.
