The thermal conditions introduced by EST resulted in a phase transformation from ␣ to ␤. The fraction of ␤ phase decreased from 25.27% to 19.47% after EST for 0.02 s, which was

The energy introduced by EST resulted in changes to the direction and intensity of texture within the microstructure with the texture intensity of the ␣ phase increasing from 4.94 to 8.52, and that of ␤ both increased from 3.35 to 9.88 after 0.04 s EST.
