The Application of Phase-field Models to Microstructure Evolution in Multi-phase and Multi-component Alloys

主讲人 : Prof. Nele Moelans

Phase-field models hold great promise as a powerful tool for computer-aided design and optimization of multi-component alloys. They can simulate the evolution of complex, multi-phase microstructures during processes such as phase transformations, deformation and annealing. They account for various phenomena, including bulk and grain boundary diffusion, transformation strains, and anisotropy in bulk and interface properties. However, a detailed de ion of the model parameters as a function of composition is required to obtain quantitative results, but often difficult to obtain and computationally expensive to handle in the simulations.

This presentation will discuss the latest advancements in phase-field modeling for multi-component and multi-phase alloys allong with the remaining challenges. It will illustrate the advantages of integrating phase-field models with machine learning and other data driven approaches, and demonstrate the importance of accounting for composition dependence in the simulations.
