To the author's knowledge, the nonlinear dynamics of inhomogeneous morphological evolution during spinodal decomposition and ordering including the subsequent coarsening process in a ternary system has not been extensively investigated. To predict morphological evolution in an inhomogeneous system without a priori assumptions on the transformation sequence and morphologies, they have to resort to computer simulations. The main objective of this work is, therefore, to develop a computer simulation technique which can predict microstructural evolution during ordering and spinodal decomposition in ternary alloys. Since the present kinetic model is microscopic in nature, it can be applied to model both ordering and phase separation as well as simultaneous ordering and phase separation. The elastic energy effect on the decomposition kinetics can also be easily incorporated into the model. As an example, a computer simulation of isostructural spinodal decomposition in a ternary alloy was performed in a simple two-dimensional square lattice.
