The phase field method is frequently employed to simulate evolution
of rather complex microstructures. In order to accurately describe the
real kinetics of a specific material system, the phase field parameters
must be calibrated to standard thermodynamic quantities such
as interface mobilities or interface energies. This letter presents
a convenient method, based on thermodynamic modelling of
shrinking of a single grain embedded in single crystal (matrix), how
to calibrate the phase field parameters. It also shows, how the required
thermodynamic quantities can be met by proper rescaling of a phase
field simulation carried out for given phase field parameters.
