Although a large number of studies on the {alpha}/{beta} phase transformation in titanium alloys have been reported, only a few works deal with the texture change observed during the {alpha}{yields}{beta} transformation during continuous heating. This is due to the difficulty to obtain information about the metallurgical state of the high temperature {beta} phase, which is not stable at room temperature. In pure titanium, the hcp {alpha} phase generally transforms into the bcc {beta} phase according to the Burgers relation with sometimes orientation variant selections. In the case of Ti-6Al-4V alloy, the transformation of the {alpha} phase is performed in the presence of a low volume fraction of {beta} phase which can influence the transformation mechanism. In the present paper, the {alpha}{yields}{beta} texture change of Ti-6Al-4V material is characterized using adapted methods. The resulting textures allows us to discuss the influence of the residual {beta} phase on the transition texture.
