Effect of internal stresses in cold rolled IF steel on the orientations ofrecrystallized grains

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