Effect of strain states during cold rolling on the recrystallized grain size in an aluminum alloy

Abstract

The evolution of texture and microstructure during recrystallization was tracked for a number of differently cold-rolled aluminum sheets and through-thickness layers which were differentiated by different strain states due to prior deformation. The results substantiate a correlation between recrystallization texture and the amount of shear applied during cold rolling as well as a decrease in the final grain size with increasing effective strain during deformation.
