Grain structure, grain growth and evolution of the grain boundary network in polycrystalline materials: theory, simulations, and experiments

Abstract: Most technologically useful materials are polycrystalline microstructures composed of myriad small monocrystalline cells/grains separated by grain boundaries/interfaces. Grains and grain boundaries play a crucial role in determining the properties of materials across multiple scales.

One method by which the grain structure is engineered is through grain growth or coarsening of a starting structure. Grain growth can be viewed as the evolution of a large metastable network, and can be mathematically modeled by a set of deterministic local evolution laws for the growth of an individual grain combined with stochastic models to describe the interaction between grains. Thus, to develop a predictive and prescriptive theory for polycrystalline materials, investigation of a broad range of statistical measures for microstructure evolution during grain growth is needed. In this talk, we will discuss recent progress on modeling, simulation, analysis and experiments of the evolution of the grain boundary network in polycrystalline materials.

Global Seminar on Mathematical Modeling and Applications

Series comments: Description: Occasional seminar on mathematical modeling and related topics

In light of the worldwide cancellations of meetings workshops and conferences many of us are forced to switch to online mode of communication. Thus following the example of many other initiatives we decided to organize a Global Seminar on Mathematical Modeling and Applications.

Zoom links will appear on the seminar website 15 minutes before talks begin so that we may convene a little earlier, get acquainted and/or catch-up.

Additionally here you can subscribe to the mailing list.
