This $400,000 Project Grant awarded by the National Science Foundation (NSF) Engineering program (CFDA 47.041) supports research to systematically understand the dislocation-phonon drag regime in metallic materials across a wide range of strain rates. The research aims to develop a novel, small-scale, high-throughput approach to study the characteristics of dislocation-phonon interactions in metals and alloys at extremely high deformation rates. The integrated experimental-computational framework will be used to study the effect of alloying elements, their concentration, and grain size on the dislocation-phonon drag regime. This understanding can enable the design of new alloys that can suppress catastrophic failures at high deformation rates, with potential applications in the defense, automotive, and aerospace industries. The award also includes plans for training, education, outreach, and dissemination activities to promote diversity, equity, and inclusion among K-12 and undergraduate students from underrepresented groups. The project is expected to run from Sep 1, 2024 to Aug 31, 2027.
