This project seeks to advance the community’s understanding of microtextured regions in titanium alloys, including their quantitative characterization – a topic that is considered to be a Grand Challenge.
In this effort, a team will: develop experimental and modeling tools to support 3D characterization of microstructure using multiple NDE modalities; validate the 3D results using 2D approaches; integrate modeling and data pipelines with MTR (and surrogate) instantiations; and study whether measurement interpretations can be enhanced with state-of-the-art materials science processing or and theory.
