%X Microstructure and texture evolution as well as phase transformations in Ti–46Al–9Nb sheet material tensile tested between 700 and 1000 °C have been analyzed. Up to not, vert, similar850 °C the microstructure shows characteristic deformation features such as mechanical twins and deformation bands. The texture, presented as inverse pole figures, contains pure deformation components, i.e. <001>, <111> and not, vert, similar<301>. Above 900 °C dynamic recrystallization becomes the dominant process. Bulged grain boundaries can clearly be distinguished in the microstructure of the tensile specimens, and the pure deformation orientation maxima <001> and <301> disappears from the texture map in favor of a new recrystallization component around <100>. Under constant temperature conditions the size of dynamically recrystallized grains is influenced by the applied strain rate. Under certain test conditions a α2 → ω/B82  phase transformation can be observed. This process is enhanced by stress and depends strongly on temperature and time or strain rate.
