Texture Evolution and Phase Transformation in Titanium Investigated by <Emphasis Type="Italic">In-Situ</Emphasis> Neutron Diffraction

Time-of-flight neutron diffraction was used to study in-situ texture evolution and the α → β phase transformation in cold-drawn titanium upon continuous heating. The texture changes in the α phase at elevated temperatures upon recrystallization are presented. For the first time, a transient β texture was observed during the α → β transformation, as indicated by the initial rise and the final drop of the {110} _β reflection intensity. This unusual observation is explained in terms of competitive growth between inter- and intragranular β allotriomorphs.
