"Computational Approach to Compositionally Complex Materials "

Diego Ibarra , University of Virginia
[Host: Joe Poon]

High Entropy Alloys (HEAs), also known as Compositionally Complex Alloys (CCAs), embody a transformative class of materials consisting of at least four elemental components. These new types of material open new horizons in alloy design for exploring new structural and functional material properties unknown in traditional alloys. However, the combinatorial nature of HEAs can result in compositional possibilities reaching into the billions or even trillions, making traditional studies challenging. This talk presents an in-depth exploration of HEAs, starting with a foundational understanding of their unique characteristics and the importance of their complex phase behavior. It highlights the inherent challenges posed by the expansive compositional space and limitations of conventional materials discovery and design methodologies. The talk emphasizes the pivotal role of computational techniques that provides a strategic blueprint for high-throughput alloy design that accelerates the exploration and optimization of HEAs but also provides a deeper insight into their fundamental behaviors.
