Precipitation hardening provides one of the most widely used mechanisms for the strengthening of nickel-based superalloys. Modeling of precipitation process plays an important role in understanding the temporal evolution of microstructure and the corresponding responses of mechanical properties of nickel-based superalloys. However, precipitation is a complex process involving the simultaneous occurrence of nucleation, growth and coarsening. Accurate modeling of the precipitation process requires a synchronous consideration of all these contributions. Moreover, the phase equilibrium information as well as the mobility data of matrix phase needs to be constantly updated as the nucleation, growth and coarsening proceed. Such a simulation, therefore, necessitates a smooth integration of thermodynamic calculation, kinetic simulation and property modeling of the material. In this Presentation, we will present the simulation tool we have developed in this regard, and commercial nickel-based superalloys will be used as examples to demonstrate the applications of this modeling tool.
