Abstract
Interface equations of motion for a single tetragonal nucleus growth and for twin formation under elastic fields in cubic-tetragonal structural transitions are derived. We give an expression to the elastic energy in the form of non-local, long-range interactions between nonconserved order parameters. We find that a single tetragonal nucleus grows anisotropically into oval or square and that twin structure is a stationary state in the coarsening process. These results are consistent with the numerical simulation.
