Kinetics of Recrystallization in Cold Rolled

The cold rolling of metal sheets leads to the formation of an inhomogeneous microstructure and texture. The type and sharpness of texture through the thickness and the degree of inhomogeneity depend on the friction between rolls the rolled material and the geometry of the rolling gap. In order to follow the effect of friction, two kinds of stecimens were prepared by applying with and without lubrication during the cold rolling. Although the deformed microstructure of the specimens rolled without lubrication was much inhomogenous than that of the specimens rolled with lubrication, the effect of lubrication on the cold rolling texture was not found. the recrystallization behavior was strongly dependent on the deformation process. Thus, the retardation of the recrystallization was observed in the specimens rolled without lubrication.
