A modeling framework for phase field simulation of multi-component alloys

The phase field method (PFM) has become an important modelling technique in computational materials science for simulating microstructural evolution. It has been used to simulate a wide variety of phase transformation processes including solid-state reactions, solidification and dendrite formation, grain-growth, plastic deformation, and so on processes. Although PFM has received increasing prominence in recent years for full-field descriptions of microstructures, its applications to multi-component industrial alloys are rather limited due to the lack of an efficient way to obtain instant update of the needed thermodynamic and diffusivity data. Since CALPHAD method has been very successful in predicting phase equilibria of multi-component alloys, it is essential to develop a modeling framework that allows seamless and efficient integrations between PFM and CALPHAD modeling tools to apply PFM to commercial alloys. In this presentation, we will present the modeling framework, PanPhaseField, we recently developed. Its unique design and features, as well as application examples will be presented.
