Statistical models of primary recrystallization are described. Particularly the superposition model and the compromise model must be distinguished. Both models are able to consider oriented nucleation, orientation dependence of driving force, and misorientation dependence of boundary mobility. The superposition model requires abundant nucleation, whereas the compromise model corresponds to sparse nucleation. In order to model the two-step recrystallization observed in low carbon steel the compromise model was generalized for the case of inhomogeneous (two-step) recrystallization. The compromise model was applied to the recrystallization textures of fcc-copper type and brass-type metals as well as to bcc-metals, i.e. low carbon steel. All these textures are well represented by the model on the basis of experimentally established input parameters, i.e. the growth laws 40°111, 27° + 84°110 and α111 respectively for fcc- and bcc- metals.
