Local boundary migration during recrystallization in pure aluminium

    Research output: Contribution to journalJournal articleResearchpeer-review


    Boundary migration during recrystallization has been followed by an ex situ electron channelling contrast technique, and protrusions/retrusions formed locally on recrystallization boundaries have been quantified. The results show that the motion of recrystallization boundaries is much more complex than generally appreciated. Locally protrusions/retrusions can provide a driving force comparable in magnitude to the driving force from the stored energy in the deformed matrix. The stop–go motion of the recrystallization boundaries is also discussed and related to the formation of protrusions and retrusions.
