| Abstract Scope |
Professor Tony Rollett has made numerous contributions to our understanding of microstructural development. In this talk I consider the ubiquitous phenomenon of abnormal grain growth (AGG), which involves the unusually rapid growth of a minority of constituent grains and often has a deleterious impact on the thermo-mechanical properties of a system. I will first describe some joint work with Tony on the use of machine learning in the form of a canonical-correlation analysis (CCA) to connect AGG in ceramics with powder processing and, more specifically, the chemistry of specialty ceramics. I next examine the kinetics of evolving synthetic and experimental microstructures, as quantified by their embodied information, to identify temporal signatures of the onset of AGG. This is accomplished by tracking the information content of coarsening microstructures via selected metrics and measures of shared information and interaction strength. Finally, I will describe an approach to predicting AGG well in advance of its occurrence. |
