Microstructural characteristics in α phase during superplastic deformation of Ti6Al4V

Microstructural characteristics of Ti6Al4V sheet material after tensile superplastic deformation were studied in the temperature range 875–950 °C and at strain rates of 5 × 10−4, 1 × 10−3 and 5 × 10−3 s−1. Specimens water quenched from the deformed state were studied by transmission electron microscopy to understand the dislocation characteristics of the α phase in terms of their generation and glide during superplastic deformation.
