Evolution of hot rolling textures in a two-phase (α2 + β) Ti3Al base alloy

Texture development during thermomechanical processing of two-phase (α2 + β) Ti-24Al-11Nb alloy was studied as a function of variables like initial microstructure, rolling temperature, cooling conditions, etc. The evolution of texture in different conditions has been critically analyzed. It has been found that unrestricted rolling of primary α2 at lower temperature leads to a good basal [0001] texture., while at higher temperatures, the α2 rarrow β rarrow α2 phase transformation leads to weakening of the basal texture. Texture of secondary α2 derived from rolled β is generally non-basal. However, the texture of secondary α2 derived from recrystallized β has a basal character
