Abstract Scope |
A grand challenge problem in engineering of polycrystals is to develop prescriptive process technologies capable of producing an arrangement of grains that provides for a desired set of materials properties. 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. This talk will address not only the challenges of generating suitable nanocrystalline film samples for experiments, but also the challenges of extracting the relevant microstructural metrics from bright-field transmission electron images and crystal orientation maps. A machine learning approach to automated grain boundary detection and integration of experiments with simulations, mathematical models and theory will be discussed. |
