Very recently, a multi-class model for simulation of recrystallization, recovery and grain growth as well as the interaction of these mechanisms with precipitation has been developed. These mechanisms are important during deformation of metallic materials at high temperatures. The corresponding algorithms have been implemented in the software package MatCalc, which is utilized in the present simulations. In this contribution, an outline of the model is given first. Then, the main features of the approach are discussed and compared to results obtained with a single-class Ansatz. Finally, application of the model is demonstrated on some selected examples in Ni-base superalloys.
