| Abstract Scope |
This paper presents a phase-field model that is consistent with the multiphase system of aluminum foam to predict the microstructural evolution involved in the foaming process of the aluminum foam and its final microstructure. The phase-field model characterizes the microstructure of the foam material with a set of material constants calibrated through experiments and molecular dynamics (MD) calculations. A series of MD simulations were performed on a group of aluminum and silicon (Al-Si) atoms, whose potentials were defined using the angular dependent potential (ADP). The MD results such as diffusion, and specific heat capacity are used as input parameters for the developed phase-field model. The developed phase field model will predict the microstructural evolution of metal foams during foaming processes and will be further used to establish a multiscale computational framework that bridges the process, structure, property and performance of metal foams. |
