Abstract

Virtual Kinetics of Materials Laboratory : Spinodal Decomposition simulates the time-dependent segregation of two chemical components and its subsequent coarsening. The resultant microstructure obeys the well-known lever rule. The default values are physical but arbitrary. The presented model is based on the phase field method (see cited literature below).
