Abnormal Grain Growth in Four Dimensions

Abstract

The long-term objective of this project is to understand the interaction between grain boundaries and second phase particles during abnormal grain growth (AGG). AGG is often seen in multi-phase materials, yet its origins and mechanisms have remained an enigma. For instance, what are the microstructural markers associated with particle-assisted AGG? How do the boundaries of the abnormal grain propagate through the particle cloud?
