The PanSolidification module is designed for the simulation of solidification behavior of multicomponent alloys under a variety of conditions with different cooling rates. It is an extension of the Scheil model taking into consideration of back diffusion in the solid, secondary dendrite arm coarsening, and the formation of eutectic structure. It is seamlessly integrated with the user-friendly Pandat Graphical User Interface (PanGUI) as well as thermodynamic calculation engine, PanEngine. The implementation of PanEngine guarantees reliable input data, such as chemical potential, phase equilibrium and mobility. . This module can predict the secondary dendrite arm spacing (SDAS), microsegregation, types and amounts of non-equilibrium phases in the solidiﬁcation microstructure of multi-component alloys by incorporating back diffusion in the solidiﬁed primary phase, as well as the undercooling and dendrite arm coarsening during solidiﬁcation.
