| Abstract Scope |
The phase field method, grounded in the diffuse interface concept, models microstructure evolution through a continuous order parameter whose spatio-temporal distribution implicitly captures interface motion. Mathematical analyses have shown that phase field equations recover sharp interface boundary conditions in the sharp and thin interface limits, ensuring physical rigor and computational efficiency. Building on this framework, our group has developed phase field models for a broad range of microstructural phenomena, including texture evolution, recrystallization, sintering with phase transformations, and generalized phase transformations via direct links to CALPHAD based thermodynamic databases. We have also applied these models to map corrosion potential distributions based on predicted microstructures and phase/solute distributions, supporting the design of corrosion-resistant alloys. In this presentation, we will introduce our modeling strategies, key numerical implementations, and representative results, demonstrating how our phase field platform provides a versatile tool for interpreting and predicting complex microstructural evolution. |
