Effects of Widening during Rolling on the Subsequent Recrystallization Kinetics of Copper

Abstract

Abstract. Recrystallization kinetics in copper cold-rolled to 90% reduction, with and without significant widening, was investigated by electron backscatter diffraction. It was found that the recrystallization process was slightly retarded, and the development of the cube recrystallization texture was largely inhibited in the widening sample. Cube grains were observed to have a growth advantage by a factor of 2 in the non-widening sample, while this growth advantage was not observed in the widening sample. The development of the cube texture in the two samples is discussed.

Importance of Non-uniform Boundary Migration for Recrystallization Kinetics

“…The width of the rolling plate was wide enough to avoid any obvious sample widening during rolling [26].…”
