The focus of Alison’s research project is to develop a phenomenologically-based understanding of the fatigue behavior in titanium alloys. This project will play a critical role in the development of methods for the accelerated implementation of aeronautical materials. She will be working with Ti-6Al-4V alloy, and will use stereological procedures to develop a quantitative database that relates the fatigue properties of the alloy to its key microstructural features. The resulting database will be used to build neural network and fuzzy logic models to identify the specific microstructural features that have the greatest impact on the fatigue life of the material, as well as to predict fatigue properties based on microstructural parameters. Alison’s research is supported by the STW-21 effort, and much of her work will be done in conjunction with the Materials Laboratories at Wright-Patterson Air Force Base.
