show that the recrystallized grains are present near the original grain boundaries and exhibit similar orientation to the deformed grain. Strain-induced boundary migration is likely the mechanism for dynamic recrystallization. The low density of Al3Zr dispersoids near grain boundaries can make contribution to strain-induced boundary migration. Key words: aluminum alloy; Zener-Hollomon parameter......

. Key words: aluminum; recrystallization; texture; recovery; stored energy; boundary migration 1 Introduction It is known that grain boundary mobility in aluminum is misorientation dependent, and the velocity of boundary migration could reach the maximal value if the misorientation between two neighboring grains is characterized by a rotation around <111> axis about 40°, i.e. 40°<111>......
