Abstract
Computer simulations of phase decomposition were performed for the Cu-Co alloy system on the basis of the non-linear diffusion equation. In the calculations, the modified regular solution approximation was adopted, i.e. the composition and temperature dependences of the interaction parameter, Ω, between the nearest neighbour atoms were taken into account and the mobility of atoms was defined as a function of solute composition. The phase decompositions were successfully computed for the Cu-Co alloys. The calculation method proposed here is applicable to many actual alloy systems.
