Discovering Microstructure-Property Relationships in Metallic Materials through Latent Space Mapping of Plasticity and Diffraction  

Abstract:  Mechanical properties are often governed by the plastic flow within the material heterogeneous microstructure, spanning from the nanoscale to the macroscale. Rapidly capturing the interactions between metal plasticity and microstructure is, therefore, critical to accelerating materials discovery and design. Experimental advances have equipped researchers with high-resolution tools capable of mapping plasticity and microstructure. Techniques like Electron Backscatter Diffraction (EBSD) provide rapid, detailed characterization of microstructural variations, while High-Resolution Digital Image Correlation (HR-DIC) allows nanometer-scale tracking of plastic deformation over large fields of view during mechanical loading. However, linking these large full-field datasets to macroscopic properties requires innovative analytical frameworks that can efficiently extract underlying structure-property relationships.

In this work, we develop a transformative methodology to encode and map microstructural and plasticity information into a latent feature space, compressing the data to its most governing features while maintaining spatial information. This approach identifies specific microstructural and plasticity heterogeneities that drive mechanical behavior, ultimately enabling the rapid prediction of mechanical properties. By unveiling these critical structure-property relationships, our study allows accelerated discovery and design of metallic materials with tailored mechanical properties.

Bio: I am an assistant professor in Materials Science and Engineering at UIUC. I hold a Ph.D. in Solid Mechanics, Materials Science, and Mechanical Engineering. In 2012, I joined the research group of T.M. Pollock at the University of California Santa Barbara (UCSB), where I became a Specialist in 2015. I received the Hetényi Award in 2018 and 2024, which is given annually for the best research paper published in Experimental Mechanics. I have also been recognized for my contribution to understanding the fatigue properties of metals and was awarded the Superalloy2018 Best Paper Award. In 2024, I received the NSF Career Award and the Kent D. Peaslee Faculty Award. My research interests include metallic materials' mechanical and environmental performance for high temperature, energy, space, and environmental applications. I also focus on high-throughput and advanced data analysis-based characterization methods to accelerate material discovery.
