## What is/are Multiphase Field?

Multiphase Field - Mesoscale simulation of microstructure evolution can be done effectively using the multiphase field (MPF) method.^{[1]}Based on these results, the microstructure formation process was simulated in duplex stainless steel using a multiphase field (MPF) method.

## multiphase field theory

A multiphase field theory and corresponding finite element simulations are developed to describe ferroelastic domain switching in bulk polydomain tetragonal zirconia (t′-zirconia).^{[1]}A novel multiphase field theory for ferroelectric systems in the vicinity of a polymorphic phase boundary (PPB) is developed by coupling the Landau-Devonshire thermodynamic potentials of the individual phases.
