| Abstract Scope |
This talk will focus on the application of phase field modeling to study template-directed eutectic solidification, in which a melt at the eutectic composition is solidified in a confined environment of the template with regular structure. Microstructures with patterns emerges during the solidification process due to the interactions between the solidification front and the template surfaces, along with the lamellar pattern that arises naturally from eutectic solidification. We will describe the insights provided by phase field simulations on how the template induces reorientation of the lamellae, how the morphologies change from lamellae to ring-like patterns, and finally how Archimedean lattices arises, as well as how all these structures can be tuned by the processing conditions (e.g., solidification velocity) and the template geometry. We will also highlight the application of PRISMS-PF to solidification, an open-source framework for phase-field simulations of microstructure evolution, developed with an emphasis on performance, flexibility, and ease-of-use. |
