Effect of Internal Stresses in Cold Rolled IF Steel on the Orientations of Recrystallized Grains

Abstract

The residual stress remaining in deformed matrix is evaluated on the basis of the active slip systems and the dislocations necessary for flow. The orientations of the recrystallized grains that are expected to grow preferentially in the internally stressed matrix are predicted by means of a new recrystallization model. The model involves two principles: i) a strain energy release maximization theory and ii) growth by {110} plane matching. The predictions obtained in this way are compared with experimental results and discussed in terms of the possible effect of the internal stresses produced by cold rolling on the recrystallization texture.
