Title: Design of Advanced Materials for Extreme Dynamic Environments
Speaker: Suhas Eswarappa Prameela, post-doctoral scholar, Hopkins Extreme Materials Institute (HEMI), John Hopkins University
The microstructure of today’s metallic alloys and composites is steadily rising in complexity because of increasing demands in performance. Designing better materials for extreme dynamic environments has benefits cutting across many areas: automobile frames, vehicle/body armor protection parts, aircraft components, satellite systems, and multifunctional hypersonic structures. In this talk, I will describe our design of unique thermo-mechanical processing pathways for several model Mg alloys, where nucleation-controlled kinetics dominate the microstructural evolution. Synergistic experimental and computational efforts unravel fundamental ways to strategically tune atomic-scale defects to generate fine solute clusters and achieve a high density of nanoscale precipitates. These novel microstructures show great promise in dramatically improving Mg alloy properties across diverse, dynamic environments. Within this presentation, I will also highlight the Materials and Data for Extreme Environments (MDEE) project, a new materials informatics effort for enabling the high-throughput inverse design and manufacturing of advanced materials.
