Paper Title:
In-Situ EBSD Observation of the Recrystallization of an IF Steel at High Temperature
  Abstract

Recrystallization phenomena in an interstitial free (IF) steel have been investigated by in-situ annealing in the SEM, combined with Electron Back Scattered Diffraction (EBSD) mapping. Sequential recrystallization phenomena, such as initiation and growth of new grains, are clearly distinguished by EBSD mapping at temperatures of up to 1070K. More than 70% of the recrystallized grains are of {111}<121>, {111}<123> and {111}<110> orientation. It is found that many recrystallized grains are formed from {111}<123> deformed grains at the beginning of recrystallization. It is observed that some of α-fibre (RD//<110>) orientations have difficulty in recrystallization compared to γ–fibre deformed grains. In particular, many grains of {001}<110> orientation remain un-recrystallized even after holding for 65 minutes at 1050K.
