摘要：

Recently, Khachaturyan's group proposed a new calculation method for phase decomposition on the basis of the Onsager equation. In the present study, we modified the Khachaturyan diffusion equation to allow simulation of the phase decomposition in actual alloy systems. Two-dimensional (2-D) computer calculations are performed for the phase decompositions of Al-Zn, Cu-Co, and Fe-Mo binary systems by using the thermodynamic data related to the equilibrium phase diagrams. The calculated microstructures are very similar to the actual micrographs experimentally obtained for these alloys.
