This $289,939 Project Grant awarded by the National Science Foundation (NSF) under the Mathematical and Physical Sciences (CFDA 47.049) program supports collaborative research to advance the understanding of solute cluster strengthening in magnesium (Mg) alloys. The research aims to elucidate the fundamental mechanisms by which nanoscale groupings of solute atoms can dramatically improve the strength of metal alloys, compared to more conventional strengthening methods like precipitate hardening. Through a combination of advanced experimental characterization and computer simulations, the project will investigate the structure and interactions of solute clusters with dislocations, as well as quantify the resulting macroscopic yield strength enhancement. The project outcomes are expected to lead to a new theoretical model for predicting metal alloy strength based on the presence of solute clusters, with potential applications in developing stronger and lighter materials for industries like automotive and aerospace. The award also includes an educational component to engage students and the public in materials science and learning opportunities.
