The loss of strength of the material in the precipitate free zone allows propagation of cracks in the zones and causes an embrittlement of the material. Based on application of the thermodynamic extremal principle a robust model is derived, which allows the description of the kinetics of formation of the precipitate free zone. Several simulations based on the model are performed and the results are discussed.
