Abstract Scope |
Properties of materials depend on their microstructures. The evolution of microstructures is governed by the thermodynamic driving force, which can be obtained from free energy, and kinetic properties, which determine how quickly the system can respond to the driving force. This project aims to develop algorithms and software that automate and optimize the selection of thermodynamic and kinetic parameters for phase-field simulations of microstructure evolution in multicomponent systems. The current version of the software automatically sets up simulations in the PRISMS-PF numerical framework for microstructure evolution in binary alloys based on the free energies from empirical databases or atomistic simulations. Our framework relies on phase-field models that generalize easily to various multi-component, multi-phase systems, and we aim to establish convenient workflows for simplified, computationally efficient thermodynamics formulations as well as for more complex expressions present in CALPHAD databases. We also quantify the uncertainties introduced by the parameterization. |
