Abstract Scope Construction metallic materials combine strength with formability. These features are obtained for heterogeneous microstructures with hard constituents dispersed in a soft matrix. On the other hand, sharp gradients of properties between phases cause local fracture. Advanced models are needed to design microstructures with smoother gradients of their features. Models based on stochastic variables meet this requirement. Our objective was to account for the random character of the recrystallization and to transfer this randomness to equations describing evolution of dislocations and grain size. The idea of the stochastic model is presented, as well as its identification and validation.
