High-throughput strategies towards new alloys and understanding complex phenomenaFrom aerospace and propulsion to energy and sustainable manufacturing, better structural alloys are urgently needed. The available composition and processing space offers ample opportunity for alloy design. However, navigating this space is difficult, because new complex structures and phenomena emerge, and candidate alloys must satisfy numerous requirements. Using examples from my research, I present strategies to overcome these challenges: To begin, combining high-throughput experiments with data science tools allows to rapidly discover broadly applicable rules underlying complex behavior, including phase selection and glass formation. Then, I introduce the Film Inflation Method to investigate how the fragility of metallic liquids governs their solidification. Finally, closely integrating computation and experiments can rapidly push the limits of alloy performance, as demonstrated on the successful CALPHAD-based design of refractory alloys with BCC-B2 precipitation-strengthened microstructures for applications at ≥1,300°C. Altogether, these examples highlight the great potential of seamlessly integrating experiments, modeling, and data science into autonomously operating materials discovery platforms.
BiographyDr. Sebastian Kube is currently a Postdoctoral Scholar in Structural Materials at UC Santa Barbara, working with Prof. Tresa Pollock. In 2021, he earned his PhD from Yale University, advised by Prof. Jan Schroers. Sebastian is especially interested in metallic liquids and their glass forming ability, as well as Refractory Multi Principal Elements Alloys for high-temperature applications. Further, he pursues high-throughput strategies, with the vision of creating an autonomous platform for the rapid discovery of new superior alloys.
