In this presentation, we introduce a practical and scientifically sound modeling approach for precipitation simulation of multi-component alloys under the framework of ICME. In this approach, the necessary mobility data and thermodynamic properties are provided by the Calphad method. The modeling of microstructural evolution is based on the KWN approach, which considers the concurrent nucleation, growth and coarsening of multi-phase and multi-component alloys. The obtained microstructure information are key inputs for estimation of mechanical properties. Even though in the early stage, this study shows the promise of using an integrated modeling framework to comprehend the relationship between the chemistry/processing - structure - properties. The approach has been demonstrated by the precipitation simulation of a number of multi-component Ni-based superalloys and the prediction of age hardening behavior of a series of Al alloys. The preliminary results provide reasonable confidence for using such an approach to complex alloys for technological applications.
